https://hausmeisterservice-unterhaching.de/ | Response does not include the HTTP Content-Security-Policy security header or meta tag |
Vulnerability description
We noticed that the target application lacks the Content-Security-Policy (CSP) header in its HTTP responses. The CSP header is a security measure that instructs web browsers to enforce specific security rules, effectively preventing the exploitation of Cross-Site Scripting (XSS) vulnerabilities.
Risk description
The risk is that if the target application is vulnerable to XSS, lack of this header makes it easily exploitable by attackers.
Recommendation
Configure the Content-Security-Header to be sent with each HTTP response in order to apply the specific policies needed by the application.

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.

https://hausmeisterservice-unterhaching.de/ | 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`.
Classification

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).

https://hausmeisterservice-unterhaching.de/ | 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.

https://hausmeisterservice-unterhaching.de/ | Response headers do not include the Referrer-Policy HTTP security header as well as the |
Vulnerability description
We noticed that the target application's server responses lack the Referrer-Policy
HTTP header, which controls how much referrer information the browser will send with each request originated from the current web application.
Risk description
The risk is that if a user visits a web page (e.g. "http://example.com/pricing/") and clicks on a link from that page going to e.g. "https://www.google.com", the browser will send to Google the full originating URL in the `Referer` header, assuming the Referrer-Policy header is not set. The originating URL could be considered sensitive information and it could be used for user tracking.
Recommendation
The Referrer-Policy header should be configured on the server side to avoid user tracking and inadvertent information leakage. The value `no-referrer` of this header instructs the browser to omit the Referer header entirely.

Website is accessible.
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.

Evidence
We managed to detect a publicly accessible MySQL service. PORT STATE SERVICE VERSION 3306/tcp open mysql MySQL 5.5.5-10.6.22-MariaDB-0ubuntu0.22.04.1-log
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
We managed to detect a publicly accessible Windows Server Message Blocks (SMB) service. PORT STATE SERVICE VERSION 139/tcp open netbios-ssn Samba smbd 4.6.2
Vulnerability description
We found that the Windows Server Message Blocks (SMB) service is publicly accessible. The Server Message Block (SMB) protocol facilitates services like file and print sharing on systems. Older SMB protocol versions operate through NetBIOS to enable application-layer networking for devices within Windows operating systems, including communication with printers and serial ports.
Risk description
Exposing this service online can enable attackers to launch authentication attacks, like guessing login credentials, potentially gaining unauthorized access. Attackers might use publicly available employee information for brute-force attacks. Vulnerabilities, such as unpatched software or protocol flaws, could also be exploited. An example is MS17-010 (EternalBlue) vulnerability. Additionally, integration with Active Directory Domain Services could allow attackers to move laterally across the network, accessing more systems and sensitive data.
Recommendation
We recommend turning off SMB access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). Avoid permitting direct user authentication to Active Directory over the Internet to prevent attackers from engaging in password guessing or causing the lockout of legitimate domain user accounts. If the SMB service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall.

Vulnerability description
We found that the SSH service with username/password authentication is publicly accessible. Network administrators often use remote administration protocols to control devices like switches, routers, and other essential systems. However, allowing these services to be accessible via the Internet can increase security risks, creating potential opportunities for attacks on the organization.
Risk description
Exposing this service online with username/password authentication can enable attackers to launch authentication attacks, like guessing login credentials, and potentially gaining unauthorized access. Vulnerabilities, such as unpatched software, protocol flaws, or backdoors could also be exploited. An example is the CVE-2024-3094 (XZ Utils Backdoor) vulnerability.
Recommendation
We recommend turning off SSH with username/password authentication access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the SSH service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, it is advisable to utilize SSH Public Key Authentication since it employs a key pair to verify the identity of a user or process.
Evidence
Domain Queried | DNS Record Type | Description | Value |
---|---|---|---|
_dmarc.hausmeisterservice-unterhaching.de | TXT | Text record | "v=DMARC1; p=none;" |
Vulnerability description
We found that the DMARC record for the domain is not configured with sp policy, meaning that no policy is enforced for subdomains. When a DMARC record does not include a subdomain policy (sp directive), subdomains are not explicitly covered by the main domain's DMARC policy. This means that emails sent from subdomains (e.g., sub.example.com) may not be subject to the same DMARC enforcement as the main domain (example.com). As a result, attackers could potentially spoof emails from subdomains without being blocked or flagged, even if the main domain has a strict DMARC policy.
Risk description
Without a subdomain policy (sp directive) in the DMARC record, subdomains are not protected by the same DMARC enforcement as the main domain, leaving them vulnerable to spoofing attacks. This inconsistency can be exploited by attackers to send phishing emails from subdomains, undermining the organization’s overall email security.
Recommendation
To mitigate the risk, we recommend configuring the DMARC record with a subdomain policy by adding the sp=reject or sp=quarantine directive. This will extend DMARC enforcement to all subdomains, preventing spoofing attempts and maintaining consistent security across both the main domain and its subdomains.
Evidence
We checked 2056 selectors but found no DKIM records.
Vulnerability description
We found that no DKIM record was configured. When a DKIM (DomainKeys Identified Mail) record is not present for a domain, it means that outgoing emails from that domain are not cryptographically signed. DKIM is a critical component of email authentication, allowing recipients to verify that an email was genuinely sent from an authorized server and that the message has not been altered in transit. The absence of a DKIM record leaves the domain vulnerable to email spoofing and phishing attacks, as attackers can send fraudulent emails that appear to originate from the domain without any cryptographic verification.
Risk description
Without a DKIM record, recipients have no way of verifying the integrity or authenticity of emails sent from the domain. This increases the likelihood of phishing and spoofing attacks, where malicious actors impersonate the domain to send fraudulent emails. This can lead to significant security incidents, such as credential theft, financial fraud, or the distribution of malware. Additionally, many email providers use DKIM as part of their spam and reputation filters, meaning that emails from a domain without DKIM may be flagged as spam or rejected, impacting the deliverability and reputation of legitimate emails.
Recommendation
We recommend implementing DKIM for your domain to enhance email security and protect your brand from email-based attacks. Generate a DKIM key pair (public and private keys), publish the public key in the DNS under the appropriate selector, and configure your email servers to sign outgoing messages using the private key. Ensure that the DKIM key length is at least 1024 bits to prevent cryptographic attacks. Regularly monitor DKIM signatures to ensure the system is functioning correctly and update keys periodically to maintain security.
Evidence
Domain Queried | DNS Record Type | Description | Value |
---|---|---|---|
_dmarc.hausmeisterservice-unterhaching.de | TXT | Text record | "v=DMARC1; p=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
We managed to detect that MySQL has reached the End-of-Life (EOL).
Version detected: 5.5.5-10.6.22-mariadb-0ubuntu0.22.04.1-log End-of-life date: 2020-04-11 Latest version for the cycle: 5.5.68 This release cycle (5.5) does have long-term-support (LTS). The cycle was released on 2012-04-11 and its latest release date was 2020-05-06.
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.

_dmarc.hausmeisterservice-unterhaching.de | TXT | Text record | "v=DMARC1; p=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.

_dmarc.hausmeisterservice-unterhaching.de | TXT | Text record | "v=DMARC1; p=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: ns5.kasserver.com, ns6.kasserver.com
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.

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.
