CVE-2022-44949 is a stored cross-site scripting (XSS) vulnerability identified in Rukovoditel version 3.2.1, specifically within the 'Add New Field' functionality located at the URL path /index.php?module=entities/fields&entities_id=24. The vulnerability arises because the application fails to properly sanitize user input in the 'Short Name' field, allowing an attacker to inject malicious scripts or HTML code that is stored persistently on the server. When other users access the affected page or entity, the malicious payload executes in their browsers under the context of the vulnerable web application. This can lead to unauthorized actions such as session hijacking, defacement, or redirection to malicious sites. The CVSS 3.1 base score is 5.4 (medium severity), with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, indicating that the attack can be launched remotely over the network with low attack complexity, requires the attacker to have some privileges (PR:L) and user interaction (UI:R), and impacts confidentiality and integrity with a scope change (S:C). No known exploits are currently reported in the wild, and no official patches or vendor details are provided. The vulnerability is classified under CWE-79, which covers improper neutralization of input leading to XSS. Stored XSS is particularly dangerous because the malicious payload is saved on the server and can affect multiple users over time, increasing the attack surface compared to reflected XSS. Given the nature of Rukovoditel as a web-based project management or CRM tool, exploitation could allow attackers to compromise user accounts, steal sensitive data, or manipulate application behavior within affected organizations.

For European organizations using Rukovoditel v3.2.1, this vulnerability poses a moderate risk primarily to confidentiality and integrity of data. Attackers with limited privileges could inject malicious scripts that execute in the browsers of other users, potentially leading to session hijacking, credential theft, or unauthorized actions within the application. This could result in data leakage, unauthorized data modification, or disruption of business processes. Since Rukovoditel is often used for project management and CRM, sensitive business and customer information could be exposed or manipulated. The scope change in the CVSS vector indicates that the vulnerability affects components beyond the initially vulnerable module, potentially impacting other parts of the application. Although availability is not directly affected, the indirect consequences of data compromise or trust erosion could be significant. The requirement for some privileges and user interaction limits the ease of exploitation but does not eliminate risk, especially in environments with many users or weak internal controls. The absence of known exploits in the wild suggests limited active targeting currently, but the stored nature of the XSS means that once exploited, the impact can persist and affect multiple users over time.

To mitigate CVE-2022-44949, European organizations should implement the following specific measures: 1) Apply input validation and output encoding: Ensure that all user inputs, especially in the 'Short Name' field and similar input points, are properly sanitized and encoded before storage and rendering. Use established libraries or frameworks that automatically handle XSS prevention. 2) Implement Content Security Policy (CSP): Deploy a strict CSP header to restrict the execution of unauthorized scripts and reduce the impact of any injected payloads. 3) Enforce least privilege: Limit user permissions so that only trusted users can add or modify fields, reducing the risk of malicious input injection. 4) Conduct regular code reviews and security testing: Perform manual and automated security assessments focusing on input handling and stored XSS vectors. 5) Monitor logs and user activity: Detect unusual behavior that might indicate exploitation attempts, such as unexpected script execution or data access patterns. 6) Educate users: Train users to recognize suspicious behavior and avoid interacting with unexpected prompts or links. 7) If possible, upgrade or patch: Although no official patch is currently listed, monitor vendor announcements or community advisories for updates addressing this vulnerability. 8) Use web application firewalls (WAFs): Configure WAF rules to detect and block common XSS payloads targeting the affected endpoints. These measures combined will reduce the likelihood of exploitation and limit the potential damage if an attack occurs.
