Vulnerability description

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.

Vulnerability description

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`.

Vulnerability description

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.

Vulnerability description

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

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).

Vulnerability description

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

Risk description

The only risk this might present nowadays is revealing debug HTTP methods that can be used on the server. This can present a danger if any of those methods can lead to sensitive information, like authentication information, secret keys.

Recommendation

We recommend that you check for unused HTTP methods or even better, disable the OPTIONS method. This can be done using your webserver configuration.

Vulnerability description

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.

Vulnerability description

Risk description

These endpoints may represent an attack surface for malicious actors interested in API-specific vulnerabilities.

Recommendation

Use the API Scanner to perform a more thorough vulnerability check for these endpoints, if an API specification is present.

Vulnerability description

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

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.

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.

Vulnerability description

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.

Vulnerability description

Risk description

Without a DMARC policy, your domain is highly vulnerable to email spoofing, allowing attackers to impersonate your brand and send fraudulent emails that appear legitimate. This can lead to phishing attacks targeting your customers, employees, or partners, potentially resulting in stolen credentials, financial loss, or unauthorized access to sensitive systems. Additionally, repeated spoofing attempts can severely damage your brand's reputation, as recipients may lose trust in communications from your domain, associating your brand with malicious activity. The absence of DMARC also prevents you from monitoring and mitigating email-based attacks, leaving your domain exposed to ongoing abuse.

Recommendation

We recommend implementing a DMARC policy for your domain. Start by configuring a DMARC record with a policy of p=none, which will allow you to monitor email flows without impacting legitimate emails. This initial setup helps identify how emails from your domain are being processed by recipient servers. Once you’ve verified that legitimate emails are passing SPF and DKIM checks, you can gradually enforce stricter policies like p=quarantine or p=reject to protect against spoofing and phishing attacks. Additionally, include rua and ruf email addresses in the DMARC record to receive aggregate and forensic reports. These reports will provide valuable insights into authentication failures and help you detect any spoofing attempts.

Vulnerability description

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.

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.
