CVE-2022-44950 is a stored cross-site scripting (XSS) vulnerability identified in Rukovoditel version 3.2.1, specifically within the 'Add New Field' functionality accessible at the URL path /index.php?module=entities/fields&entities_id=24. This vulnerability arises because the application fails to properly sanitize or encode user-supplied input in the 'Name' field when adding new fields to entities. An attacker can exploit this by injecting malicious JavaScript or HTML payloads into the Name field, which are then stored persistently on the server. When other users access the affected page or entity, the malicious script executes in their browsers under the context of the vulnerable web application. This can lead to a range of impacts including session hijacking, credential theft, unauthorized actions performed on behalf of users, or delivery of further malware. The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation), a common and well-understood web security flaw. The CVSS v3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based (remote), requires low privileges (PR:L), user interaction (UI:R), and impacts confidentiality and integrity with no effect on availability. The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. No known exploits are currently reported in the wild, and no official patches or vendor advisories are linked, indicating that mitigation may rely on custom fixes or updates from the vendor. The vulnerability requires an authenticated user with at least low privileges to inject the payload, which limits exploitation to insiders or compromised accounts. However, the persistent nature of the XSS increases risk as multiple users can be affected once the payload is stored.

For European organizations using Rukovoditel 3.2.1, this vulnerability poses a moderate risk primarily to web application confidentiality and integrity. Attackers with low-level authenticated access could inject malicious scripts that execute in other users' browsers, potentially leading to session hijacking, theft of sensitive data, or unauthorized actions within the application. This could compromise internal workflows, data integrity, and user trust. Given that Rukovoditel is a project management and CRM tool, the exposure of business-critical data or manipulation of project information could disrupt operations. The vulnerability does not directly affect availability, so denial of service is unlikely. However, the requirement for authentication and user interaction reduces the likelihood of widespread exploitation. European organizations with sensitive or regulated data managed in Rukovoditel should be particularly cautious, as data breaches could trigger compliance issues under GDPR. The absence of known exploits suggests limited active targeting, but the vulnerability remains a latent risk especially if attackers gain insider access or compromise user credentials.

1. Immediate mitigation should include restricting access to the 'Add New Field' functionality to trusted administrators only, minimizing the number of users who can inject data. 2. Implement strict input validation and output encoding on the Name field to neutralize any HTML or script content before storage and rendering. This can be done by applying context-aware encoding libraries or frameworks that handle XSS prevention. 3. Conduct a thorough code review of all user input handling in Rukovoditel, especially in modules that allow data creation or modification, to identify and remediate similar injection points. 4. If vendor patches or updates become available, prioritize their deployment after testing. 5. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context, reducing the impact of any injected payloads. 6. Monitor application logs for unusual activity related to field creation or modification, which may indicate exploitation attempts. 7. Educate users about phishing and social engineering risks that could lead to credential compromise, as authenticated access is required for exploitation. 8. Consider implementing multi-factor authentication (MFA) to reduce the risk of account takeover that could facilitate exploitation.
