74cms Cross-Site Scripting (XSS) Scanner

A Cross-Site Scripting (XSS) vulnerability in 74cms can allow attackers to execute arbitrary scripts in the context of a user's browser. XSS attacks commonly exploit vulnerabilities in web application development by injecting malicious scripts, impacting user browsers negatively upon visiting affected pages. The primary aim of these scripts is to steal sensitive information, hijack user sessions, or deface web content. XSS vulnerabilities often arise due to inadequate input validation and output encoding, leading to harmful script execution within the user's browser. Such vulnerabilities can have severe repercussions including unauthorized access to user data, credentials, and other sensitive information on the impacted platform. Addressing these vulnerabilities is crucial for maintaining user trust and preserving the integrity of web applications.

The 74cms platform is susceptible to Reflected XSS, where malicious scripts are reflected off a web server back onto a user’s browser. This typically occurs when user input (such as form entries or URL parameters) are improperly validated. The vulnerable endpoint highlighted includes a script injection point in the 'jobs-list.php' page with the 'key' parameter. Attackers exploit this by crafting URLs that contain these injection points, which when accessed by a victim, execute the malicious script within their session. This lack of proper output encoding or input filtering enables scripts to persist and execute. As these scripts can be non-persistent, they require users to click specifically crafted links, highlighting the need for user awareness and secure coding practices.

If exploited, the vulnerability can have significant effects on users and the platform itself. Attackers could gain unauthorized access to user-sensitive information, including cookies and session tokens, potentially leading to identity theft or session hijacking. The exploit might also serve as a passage to execute further attacks, like stealing credentials or performing unauthorized actions on behalf of users. Such breaches can lead to loss of user trust, financial losses, legal repercussions for non-compliance with data protection laws, and tarnished brand reputation. Therefore, safeguarding against these vulnerabilities is essential to protect users and ensure the platform’s integrity.
