Vulnerability description
Outdated or vulnerable software components include versions of server-side software that are no longer supported or have known, publicly disclosed vulnerabilities. Using outdated software significantly increases the attack surface of a system and may allow unauthorized access, data leaks, or service disruptions. Vulnerabilities in these components are often well-documented and actively exploited by attackers. Without security patches or vendor support, any weaknesses remain unmitigated, exposing the application to risks. In some cases, even after patching, the reported version may remain unchanged, requiring manual verification.
Risk description
The risk is that an attacker could search for an appropriate exploit (or create one himself) for any of these vulnerabilities and use it to attack the system. Since the vulnerabilities were discovered using only version-based testing, the risk level for this finding will not exceed 'high' severity. Critical risks will be assigned to vulnerabilities identified through accurate active testing methods.
Recommendation
In order to eliminate the risk of these vulnerabilities, we recommend you check the installed software version and upgrade to the latest version.

Vulnerability description
We have noticed that the target application has overly permissive settings in its client access policy files. The crossdomain.xml file controls the access of externally hosted Flash scripts to this website, while clientaccesspolicy.xml specifies other sites that can read content from this website - which is normally denied by the Same Origin Policy. This vulnerability arises from configurations that grant excessive permissions to clients.
Risk description
In `crossdomain.xml`, the external websites which are permitted to read content from this website via Flash are specified in the XML tag `<allow-access-from>`. If the value of this tag is too permissive (ex. wildcard), it means that any Flash script from an external website could access content from this website, including confidential information of users. If the allowed domains are too permissive (ex. wildcard) in `clientaccesspolicy.xml`, then any external website will be able to read content (including sensitive information) from this website. Flash is not supported anymore and this poses a risk only if the user's clients use older browsers, making them vulnerable to their information being accessed by a malicious external Flash script.
Recommendation
We recommend to carefully review the content of the policy file and permit access only for legitimate domains.

Vulnerability description We noticed that the communication between the web browser and the server is done using the HTTP protocol, which transmits data unencrypted over the network. Risk description The risk is that an attacker who manages to intercept the communication at the network level can read and modify the data transmitted (including passwords, secret tokens, credit card information and other sensitive data). Recommendation We recommend you to reconfigure the web server to use HTTPS - which encrypts the communication between the web browser and the server. Classification
Evidence
Vulnerability description We found that a cookie has been set without the Risk description The risk is that an attacker who injects malicious JavaScript code on the page (e.g. by using an XSS attack) can access the cookie and can send it to another site. In case of a session cookie, this could lead to session hijacking. Recommendation Ensure that the HttpOnly flag is set for all cookies. Classification
Evidence
Vulnerability description We found that a cookie has been set without the Risk description The risk exists that an attacker will intercept the clear-text communication between the browser and the server and he will steal the cookie of the user. If this is a session cookie, the attacker could gain unauthorized access to the victim's web session. Recommendation Whenever a cookie contains sensitive information or is a session token, then it should always be passed using an encrypted channel. Ensure that the secure flag is set for cookies containing such sensitive information. Classification
Evidence
Vulnerability description We noticed that the target application's server responses lack the 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. Classification
Evidence
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. Classification
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
Vulnerability description We noticed that the target application's server responses lack the 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
Evidence
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. Classification
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 8.0.42-0ubuntu0.20.04.1 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 that nginx has reached the End-of-Life (EOL). Version detected: 1.18.0 End-of-life date: 2021-04-20 Latest version for the cycle: 1.18.0 This release cycle (1.18) doesn't have long-term-support (LTS). The cycle was released on 2020-04-21 and its latest release date was 2020-04-21. 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.
