CVE-2022-44952 is a stored cross-site scripting (XSS) vulnerability identified in Rukovoditel version 3.2.1, specifically within the /index.php?module=configuration/application endpoint. The vulnerability arises from insufficient input sanitization of the 'Copyright Text' field, which allows an attacker with limited privileges (requires authentication) to inject arbitrary web scripts or HTML content. When an authenticated user clicks the "Add" button after injecting a crafted payload, the malicious script is stored and subsequently executed in the context of users viewing the affected page. This stored XSS can lead to session hijacking, defacement, or redirection to malicious sites. The CVSS v3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based (AV:N), with low attack complexity (AC:L), requires privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, and no official patches or vendor information are provided. The vulnerability is classified under CWE-79, which is the standard classification for cross-site scripting issues.

For European organizations using Rukovoditel 3.2.1, this vulnerability poses a moderate risk primarily to the confidentiality and integrity of web sessions and data. Attackers who gain authenticated access can inject malicious scripts that execute in the browsers of other users, potentially leading to theft of session tokens, unauthorized actions performed on behalf of users, or distribution of malware. This can result in data leakage, unauthorized data modification, or reputational damage. Since the vulnerability requires authentication and user interaction, the risk is somewhat mitigated but remains significant in environments with multiple users or where privilege escalation is possible. Organizations in sectors with sensitive data or regulatory requirements (e.g., GDPR) could face compliance issues if exploitation leads to data breaches. The lack of known exploits reduces immediate threat but does not eliminate risk, especially if attackers develop exploits targeting this vulnerability.

1. Immediate mitigation should include restricting access to the configuration/application module to only highly trusted administrators to reduce the attack surface. 2. Implement strict input validation and output encoding on the 'Copyright Text' field to neutralize any injected scripts. 3. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the application context. 4. Monitor logs for unusual activity related to the configuration module, especially repeated attempts to inject scripts. 5. Educate users and administrators about the risks of stored XSS and encourage cautious behavior when interacting with configuration interfaces. 6. If possible, isolate the Rukovoditel instance behind web application firewalls (WAFs) configured to detect and block XSS payloads. 7. Regularly review and update authentication and authorization controls to prevent privilege escalation that could facilitate exploitation. 8. Since no official patch is available, consider applying custom patches or workarounds that sanitize inputs until an official fix is released.
