CVE-2024-34468 is a cross-site scripting (XSS) vulnerability identified in Rukovoditel, an open-source project management and CRM platform, affecting versions before 3.5.3. The vulnerability arises from insufficient sanitization of the user_photo parameter on the 'My Page' feature, allowing attackers to inject malicious JavaScript code. When a victim user visits the compromised page, the injected script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions within the application. The vulnerability requires no prior authentication but does require user interaction, such as visiting a crafted URL or viewing a malicious profile. The CVSS 3.1 base score is 6.1, indicating medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, but user interaction needed. The scope is changed, meaning the vulnerability can affect resources beyond the vulnerable component. The impact on confidentiality and integrity is low, with no impact on availability. No known exploits have been reported in the wild, and no official patches have been linked yet, though upgrading to version 3.5.3 or later is recommended once available. The vulnerability is classified under CWE-79, which covers improper neutralization of input leading to XSS attacks.

This vulnerability can allow attackers to execute arbitrary scripts in the context of authenticated users, leading to theft of session tokens, user impersonation, and unauthorized actions within the Rukovoditel platform. For organizations relying on Rukovoditel for project management and CRM, this could result in exposure of sensitive project data, user credentials, and internal communications. While the impact on availability is none, the confidentiality and integrity of user data can be compromised. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments where social engineering or phishing is feasible. The medium severity rating reflects a moderate risk that could be leveraged as part of a broader attack chain. Organizations with many users or those integrating Rukovoditel with other systems may face increased risk due to potential lateral movement or data leakage.

Organizations should immediately review and sanitize all user-supplied input, especially the user_photo parameter, to ensure proper encoding and neutralization of HTML and JavaScript content. Implement Content Security Policy (CSP) headers to restrict script execution sources and reduce the impact of potential XSS attacks. Monitor user-generated content for suspicious scripts and employ web application firewalls (WAFs) with rules targeting XSS patterns. Educate users about the risks of clicking on untrusted links or viewing unverified profiles within the platform. Once available, promptly apply official patches or upgrade to Rukovoditel version 3.5.3 or later. Additionally, conduct regular security assessments and penetration testing focused on input validation and XSS vulnerabilities. Consider implementing multi-factor authentication to reduce the impact of compromised credentials resulting from XSS attacks.
