Web Application Vulnerabilities
Evidence
| URL | Evidence |
|---|---|
| https://nldak.nl/ | Response headers do not include the HTTP Strict-Transport-Security header |
Vulnerability description
We noticed that the target application lacks the HTTP Strict-Transport-Security header in its responses. This security header is crucial as it instructs browsers to only establish secure (HTTPS) connections with the web server and reject any HTTP connections.
Risk description
The risk is that lack of this header permits an attacker to force a victim user to initiate a clear-text HTTP connection to the server, thus opening the possibility to eavesdrop on the network traffic and extract sensitive information (e.g. session cookies).
Recommendation
The Strict-Transport-Security HTTP header should be sent with each HTTPS response. The syntax is as follows: `Strict-Transport-Security: max-age=<seconds>[; includeSubDomains]` The parameter `max-age` gives the time frame for requirement of HTTPS in seconds and should be chosen quite high, e.g. several months. A value below 7776000 is considered as too low by this scanner check. The flag `includeSubDomains` defines that the policy applies also for sub domains of the sender of the response.

Vulnerability description
We noticed that server software and technology details are exposed, potentially aiding attackers in tailoring specific exploits against identified systems and versions.
Risk description
The risk is that an attacker could use this information to mount specific attacks against the identified software type and version.
Recommendation
We recommend you to eliminate the information which permits the identification of software platform, technology, server and operating system: HTTP server headers, HTML meta information, etc.
Evidence
Vulnerability description
We found the robots.txt on the target server. This file instructs web crawlers what URLs and endpoints of the web application they can visit and crawl. Website administrators often misuse this file while attempting to hide some web pages from the users.
Risk description
There is no particular security risk in having a robots.txt file. However, it's important to note that adding endpoints in it should not be considered a security measure, as this file can be directly accessed and read by anyone.
Recommendation
We recommend you to manually review the entries from robots.txt and remove the ones which lead to sensitive locations in the website (ex. administration panels, configuration files, etc).
Evidence
| URL | Evidence |
|---|---|
| https://nldak.nl/ | Response headers do not include the X-Content-Type-Options HTTP security header |
Vulnerability description
We noticed that the target application's server responses lack the X-Content-Type-Options header. This header is particularly important for preventing Internet Explorer from reinterpreting the content of a web page (MIME-sniffing) and thus overriding the value of the Content-Type header.
Risk description
The risk is that lack of this header could make possible attacks such as Cross-Site Scripting or phishing in Internet Explorer browsers.
Recommendation
We recommend setting the X-Content-Type-Options header such as `X-Content-Type-Options: nosniff`.

Evidence
| URL | Evidence |
|---|---|
| https://nldak.nl/ | Response headers include the HTTP Content-Security-Policy security header with the following security issues: |
Vulnerability description
We noticed that the Content-Security-Policy (CSP) header configured for the web application includes unsafe directives. The CSP header activates a protection mechanism implemented in web browsers which prevents exploitation of Cross-Site Scripting vulnerabilities (XSS) by restricting the sources from which content can be loaded or executed.
Risk description
For example, if the unsafe-inline directive is present in the CSP header, the execution of inline scripts and event handlers is allowed. This can be exploited by an attacker to execute arbitrary JavaScript code in the context of the vulnerable application.
Recommendation
Remove the unsafe values from the directives, adopt nonces or hashes for safer inclusion of inline scripts if they are needed, and explicitly define the sources from which scripts, styles, images or other resources can be loaded.

Evidence
Vulnerability description
We have noticed that the server is missing the security.txt file, which is considered a good practice for web security. It provides a standardized way for security researchers and the public to report security vulnerabilities or concerns by outlining the preferred method of contact and reporting procedures.
Risk description
There is no particular risk in not having a security.txt file for your server. However, this file is important because it offers a designated channel for reporting vulnerabilities and security issues.
Recommendation
We recommend you to implement the security.txt file according to the standard, in order to allow researchers or users report any security issues they find, improving the defensive mechanisms of your server.
Infrastructure Vulnerabilities
Evidence
We managed to detect a publicly accessible MySQL service. PORT STATE SERVICE VERSION 3306/tcp open mysql MySQL 5.5.5-10.6.20-MariaDB-cll-lve
Vulnerability description
We identified that the MySQL service is publicly accessible. MySQL serves as a common database for numerous web applications and services for data storage, making it a potential prime target for determined attackers.
Risk description
The risk exists that an attacker exploits this issue by launching a password-based attack on the MySQL service. Furthermore, they could exploit zero-day vulnerabilities to obtain remote access to the MySQL database server, thereby gaining complete control over its operating system and associated services. Such an attack could lead to the exposure of confidential or sensitive information.
Recommendation
We recommend turning off public Internet access to MySQL and opting for a Virtual Private Network (VPN) that enforces two-factor authentication (2FA). Avoid enabling direct user authentication to the MySQL service via the Internet, as this could enable attackers to engage in password-guessing and potentially initiate attacks leading to complete control. However, if the MySQL service is required to be directly accessible over the Internet, we recommend reconfiguring it to be accessible only from known IP addresses.
Evidence
| Domain Queried | DNS Record Type | Description | Value |
|---|---|---|---|
| _dmarc.nldak.nl | TXT | Text record | "v=DMARC1; p=none; sp=none;" |
Vulnerability description
We found that the DMARC record for the domain is configured with sp=none, meaning that no policy is enforced for subdomains. This allows subdomains to send emails without being subject to DMARC checks, making it easier for attackers to spoof emails from these subdomains. Subdomains are often overlooked in email security, and attackers can exploit this misconfiguration to launch phishing or spoofing attacks from seemingly legitimate subdomains of a protected domain.
Risk description
When the DMARC record is configured with sp=none, subdomains are not subject to DMARC enforcement, allowing attackers to spoof emails from subdomains without being blocked. This creates a significant risk of phishing and impersonation attacks, where malicious emails appear to originate from trusted subdomains. These spoofed emails can be used to deceive users or damage the organization's reputation, undermining the security benefits of DMARC for the primary domain.
Recommendation
To mitigate the risk, we recommend that the subdomain policy should be updated to sp=reject to ensure that any email failing DMARC checks from subdomains is automatically rejected. This will help prevent unauthorized emails from being sent from subdomains, reducing the risk of spoofing and phishing. Additionally, it's important to regularly monitor DMARC reports to track email activity from subdomains and adjust policies as needed to maintain consistent security across the entire domain.
Evidence
We managed to detect a publicly accessible File Transfer Protocol (FTP) service. PORT STATE SERVICE VERSION 21/tcp open ftp ProFTPD
Vulnerability description
We found that the File Transfer Protocol (FTP) service is publicly accessible. The FTP enables client systems to connect to upload and download files. Nonetheless, FTP lacks encryption for the data exchanged between the server and the client, leaving all transferred data exposed in plaintext.
Risk description
Exposing this service online can enable attackers to execute man-in-the-middle attacks, capturing sensitive user credentials and the contents of files because FTP operates without encryption. The entirety of the communication between the client and the server remains unsecured in plaintext. This acquired information could further facilitate additional attacks within the network.
Recommendation
We recommend turning off FTP access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the FTP service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, utilizing SFTP (Secure File Transfer Protocol) is recommended as this protocol employs encryption to secure data transfers.

Vulnerability description
We found that the DKIM key length is under 1024-bit. When a DKIM (DomainKeys Identified Mail) key length is under 1024-bit, it is considered weak by modern cryptographic standards. Shorter key lengths, such as 512 or 768 bits, are vulnerable to brute-force attacks, where an attacker could potentially forge a valid DKIM signature for a domain. This undermines the entire purpose of DKIM, which is to authenticate email messages and prevent email spoofing by verifying that the message headers have not been tampered with. A DKIM key under 1024 bits significantly reduces the difficulty for attackers to break the signature.
Risk description
The primary risk of using a DKIM key with fewer than 1024 bits is that it weakens the domain's email authentication security, making it more susceptible to brute-force attacks. If an attacker successfully forges a DKIM signature, they can impersonate legitimate senders and send fraudulent or phishing emails that appear authentic to the recipient. This can lead to financial losses, reputational damage, and an increased risk of targeted attacks, as recipients are more likely to trust emails that pass DKIM verification.
Recommendation
We recommend using a DKIM key with a length of at least 1024 bits. Ideally, 2048-bit keys should be used, as they provide a higher level of security and are more resistant to brute-force attacks. Organizations should regularly audit their DKIM configurations and rotate cryptographic keys periodically to maintain security. In addition, any DKIM keys that are less than 1024 bits should be immediately replaced with stronger keys to prevent exploitation.
Evidence
We managed to detect that Exim smtpd has reached the End-of-Life (EOL).
Version detected: 4.96-58-g4e9ed49f8 End-of-life date: 2023-11-04 Latest version for the cycle: 4.96.2 This release cycle (4.96) doesn't have long-term-support (LTS). The cycle was released on 2022-06-25 and its latest release date was 2023-10-15.
Risk description
Using end-of-life (EOL) software poses significant security risks for organizations. EOL software no longer receives updates, including critical security patches. This creates a vulnerability landscape where known and potentially new security flaws remain unaddressed, making the software an attractive target for malicious actors. Attackers can exploit these vulnerabilities to gain unauthorized access, disrupt services, or steal sensitive data. Moreover, without updates, compatibility issues arise with newer technologies, leading to operational inefficiencies and increased potential for system failures. Additionally, regulatory and compliance risks accompany the use of EOL software. Many industries have strict data protection regulations that require up-to-date software to ensure the highest security standards. Non-compliance can result in hefty fines and legal consequences. Organizations also risk damaging their reputation if a breach occurs due to outdated software, eroding customer trust and potentially leading to a loss of business. Therefore, continuing to use EOL software undermines both security posture and business integrity, necessitating timely upgrades and proactive risk management strategies.
Recommendation
To mitigate the risks associated with end-of-life (EOL) software, it's crucial to take proactive steps. Start by identifying any EOL software currently in use within your organization. Once identified, prioritize upgrading or replacing these applications with supported versions that receive regular updates and security patches. This not only helps close security gaps but also ensures better compatibility with newer technologies, enhancing overall system efficiency and reliability.Additionally, develop a comprehensive software lifecycle management plan. This plan should include regular audits to identify upcoming EOL dates and a schedule for timely updates or replacements. Train your IT staff and users about the importance of keeping software up to date and the risks associated with using outdated versions. By maintaining a proactive approach to software management, you can significantly reduce security risks, ensure compliance with industry regulations, and protect your organization's reputation and customer trust.

Service detection performed. Please report any incorrect results at https://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 6.69 seconds
Vulnerability description
We found that the Post Office Protocol (POP3) service is publicly accessible and doesn’t include STARTTLS capability. Email clients use the Post Office Protocol (POP) to download emails for user accounts. Some POP servers are initially set up to operate over an unsecured protocol. When email clients download email content through this plaintext protocol, it can pose a substantial risk to the organization's network, especially depending on which user account is set to receive the emails.
Risk description
Exposing this service online can enable attackers to conduct man-in-the-middle attacks, thereby gaining access to sensitive user credentials and the contents of emails. Given that POP3 operates via a plaintext protocol, the entirety of the data exchanged between the client and server is left unencrypted. This critical information could then be leveraged in further attacks on the organization's network.
Recommendation
We recommend turning off POP3 access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the POP3 service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, activating STARTTLS capability (switching the connection to a secure communication) or utilizing Secure POP3 (POP3S) is recommended, as this protocol employs encryption.
Evidence

|---|---|---|---|
| _dmarc.nldak.nl | TXT | Text record | "v=DMARC1; p=none; sp=none;" |
Vulnerability description
We found that the DMARC record for the domain is not configured with rua tag. When a DMARC record is not configured with the rua (Reporting URI for Aggregate Reports) tag, the domain owner misses out on critical feedback regarding the domain's email authentication performance. Aggregate reports are essential for monitoring how a domain's DMARC policy is applied across various mail servers and whether legitimate or malicious emails are being sent on behalf of the domain. Without this reporting, domain administrators have no visibility into how their DMARC policy is being enforced, which hinders their ability to detect potential spoofing or authentication issues.
Risk description
The absence of rua reporting creates a significant blind spot in the domain's email security posture. Without aggregate reports, domain administrators cannot track DMARC compliance across email sent from their domain, leaving them unaware of potential misconfigurations or unauthorized use of their domain for malicious purposes, such as phishing or spoofing. This lack of visibility increases the risk of undetected spoofing attempts, which could damage the domain's reputation and lead to financial, operational, or reputational harm. Moreover, legitimate email issues, such as misaligned SPF or DKIM configurations, may also go unnoticed, affecting email deliverability.
Recommendation
We recommend configuring the rua tag in the DMARC record to receive aggregate reports from mail servers. This tag should point to a reliable email address or monitoring service capable of handling DMARC aggregate reports, such as rua=mailto:dmarc-reports@example.com. These reports provide valuable insights into how email from the domain is being treated by receiving mail servers, highlighting potential authentication issues and attempts to spoof the domain. Regularly reviewing these reports will help ensure the DMARC policy is properly enforced and that any email authentication failures are addressed in a timely manner.
Evidence
We found insecure DNS cookie usage on the following nameservers: ns.zxcs.be, ns.zxcs.eu, ns.zxcs.nl
Vulnerability description
We found that the server does not implement DNS Cookies or uses them insecurely. DNS Cookies help prevent DNS-based attacks, such as spoofing and amplification attacks.
Risk description
The risk exists because without DNS Cookies, the server is vulnerable to DNS spoofing and amplification attacks. Attackers can manipulate responses or use the server in distributed denial-of-service (DDoS) attacks, compromising network availability and security.
Recommendation
We recommend enabling DNS Cookies to prevent spoofed DNS responses. Ensure proper cookie validation is implemented to mitigate DNS amplification attacks. Regularly update DNS servers to support the latest DNS security features.

Vulnerability description
We found that the Sender Policy Framework (SPF) record for the domain is configured with ~all (soft fail), which indicates that emails from unauthorized IP addresses are not explicitly denied. Instead, the recipient mail server is instructed to treat these messages with suspicion but may still accept them. This configuration may not provide enough protection against email spoofing and unauthorized email delivery, leaving the domain more vulnerable to impersonation attempts.
Risk description
The ~all directive in an SPF record allows unauthorized emails to pass through some email servers, even though they fail SPF verification. While such emails may be marked as suspicious or placed into a spam folder, not all mail servers handle soft fail conditions consistently. This creates a risk that malicious actors can spoof the domain to send phishing emails or other fraudulent communications, potentially causing damage to the organization's reputation and leading to successful social engineering attacks.
Recommendation
We recommend changing the SPF record's ~all (soft fail) directive to -all (hard fail). The -all setting tells recipient mail servers to reject emails from any IP addresses not listed in the SPF record, providing stronger protection against email spoofing. Ensure that all legitimate IP addresses and services that send emails on behalf of your domain are properly included in the SPF record before implementing this change.

|---|---|---|---|
| _dmarc.nldak.nl | TXT | Text record | "v=DMARC1; p=none; sp=none;" |
Vulnerability description
We found that the DMARC record for the domain is not configured with ruf tag. A missing ruf (forensic reporting) tag in a DMARC record indicates that the domain owner has not enabled the collection of detailed failure reports. Forensic reports provide valuable insights into specific instances where emails fail DMARC authentication. Without the ruf tag, the domain administrator loses the ability to receive and analyze these reports, making it difficult to investigate individual email failures or identify targeted phishing or spoofing attacks that may be exploiting weaknesses in the email authentication setup.
Risk description
Without forensic reports (ruf), domain owners have limited visibility into the specifics of failed DMARC validation. This means potential malicious activity, such as email spoofing or phishing attempts, might go unnoticed until they result in more significant security breaches or reputational damage. Forensic reports allow for quick response to email abuses by providing detailed information about the failure, including the header information of the emails involved. The absence of this data hampers an organization's ability to identify and mitigate threats targeting its domain, increasing the risk of ongoing spoofing and fraud.
Recommendation
We recommend configuring the ruf tag in the DMARC record. This tag specifies where forensic reports should be sent, providing the domain owner with detailed data on DMARC validation failures. Forensic reports allow administrators to analyze why certain emails failed authentication, making it easier to fine-tune DMARC policies or address potential vulnerabilities. Ensure that the ruf email address belongs to a secure and trusted location capable of handling sensitive email data.
Evidence
| Domain Queried | DNS Record Type | Description | Value |
|---|---|---|---|
| _dmarc.nldak.nl | TXT | Text record | "v=DMARC1; p=none; sp=none;" |
Vulnerability description
We found that the target uses p=none in the DMARC policy. The DMARC policy set to p=none means that the domain owner is not taking any action on emails that fail DMARC validation. This configuration effectively disables enforcement, allowing potentially spoofed or fraudulent emails to be delivered without any additional scrutiny.
Risk description
Emails that fail DMARC checks are still delivered to recipients. This leaves the domain highly vulnerable to email spoofing and phishing attacks, as malicious actors can impersonate the domain without facing any consequences from DMARC enforcement.
Recommendation
We recommend changing the DMARC policy to p=quarantine or, ideally, p=reject to actively block or quarantine emails that fail DMARC validation. This will enhance the security of your domain against spoofing and phishing attacks by ensuring that only legitimate emails are delivered.
Evidence

Risk description
Using end-of-life (EOL) software poses significant security risks for organizations. EOL software no longer receives updates, including critical security patches. This creates a vulnerability landscape where known and potentially new security flaws remain unaddressed, making the software an attractive target for malicious actors. Attackers can exploit these vulnerabilities to gain unauthorized access, disrupt services, or steal sensitive data. Moreover, without updates, compatibility issues arise with newer technologies, leading to operational inefficiencies and increased potential for system failures. Additionally, regulatory and compliance risks accompany the use of EOL software. Many industries have strict data protection regulations that require up-to-date software to ensure the highest security standards. Non-compliance can result in hefty fines and legal consequences. Organizations also risk damaging their reputation if a breach occurs due to outdated software, eroding customer trust and potentially leading to a loss of business. Therefore, continuing to use EOL software undermines both security posture and business integrity, necessitating timely upgrades and proactive risk management strategies.
Recommendation
To mitigate the risks associated with end-of-life (EOL) software, it's crucial to take proactive steps. Start by identifying any EOL software currently in use within your organization. Once identified, prioritize upgrading or replacing these applications with supported versions that receive regular updates and security patches. This not only helps close security gaps but also ensures better compatibility with newer technologies, enhancing overall system efficiency and reliability.Additionally, develop a comprehensive software lifecycle management plan. This plan should include regular audits to identify upcoming EOL dates and a schedule for timely updates or replacements. Train your IT staff and users about the importance of keeping software up to date and the risks associated with using outdated versions. By maintaining a proactive approach to software management, you can significantly reduce security risks, ensure compliance with industry regulations, and protect your organization's reputation and customer trust.

Risk description
An initial step for an attacker aiming to learn about an organization involves conducting searches on its domain names to uncover DNS records associated with the organization. This strategy aims to amass comprehensive insights into the target domain, enabling the attacker to outline the organization's external digital landscape. This gathered intelligence may subsequently serve as a foundation for launching attacks, including those based on social engineering techniques. DNS records pointing to services or servers that are no longer in use can provide an attacker with an easy entry point into the network.
Recommendation
We recommend reviewing all DNS records associated with the domain and identifying and removing unused or obsolete records.
