CVE-2024-3262 is a medium-severity vulnerability identified in Best Practical Solutions' Request Tracker (RT) software, specifically version 4.4.1. The vulnerability falls under CWE-200, which concerns the exposure of sensitive information to unauthorized actors. RT is a widely used issue tracking and ticketing system, often employed by IT departments and security teams to manage vulnerabilities and operational tickets. The issue arises because RT stores sensitive ticket data in the browser cache. When a user accesses RT, sensitive information such as vulnerability tickets is cached locally in the browser. Critically, this cached data remains accessible even after the user logs out or the session terminates, allowing any local user with access to the device to retrieve this information. The attack vector requires local access (AV:L) and low privileges (PR:L), but no user interaction (UI:N) is needed. The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component. Although no public exploits are known, the risk is significant in environments where multiple users share devices or where devices may be physically accessed by unauthorized personnel. The vulnerability highlights a design flaw in how RT handles sensitive data caching in browsers, which could be exploited to leak confidential information about vulnerabilities and internal tickets. No official patch links are currently provided, so mitigation relies on operational controls and monitoring until a fix is released.

For European organizations, this vulnerability poses a risk to the confidentiality of sensitive ticketing data managed within RT 4.4.1. Organizations that use RT to track security vulnerabilities, incident reports, or sensitive operational issues could inadvertently expose this information to unauthorized local users. This is particularly concerning in shared workstation environments, remote work scenarios where devices may be accessed by others, or in organizations with less stringent physical security controls. Exposure of vulnerability tickets could lead to information leakage about security weaknesses before they are remediated, increasing the risk of targeted attacks. Additionally, organizations in regulated sectors (e.g., finance, healthcare, government) may face compliance risks if sensitive data is exposed. The medium severity score reflects the limited attack vector (local access required) but significant confidentiality impact. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially in insider threat scenarios or environments with weak endpoint security. European entities relying on RT for critical IT service management or security operations should prioritize addressing this vulnerability to prevent data leakage and maintain trust.

1. Restrict local access to devices running RT 4.4.1 to trusted personnel only, enforcing strict physical and logical access controls. 2. Educate users to clear browser caches regularly, especially after ending RT sessions, to minimize residual sensitive data. 3. Implement endpoint security solutions that monitor and restrict unauthorized access to browser cache files or sensitive directories. 4. Use browser configurations or extensions that limit caching of sensitive web application data or enforce private/incognito modes when accessing RT. 5. Monitor for unusual local access patterns or attempts to access cached RT data on shared devices. 6. Engage with Best Practical Solutions for updates or patches addressing this vulnerability and plan timely upgrades once available. 7. Consider isolating RT access to dedicated, secured workstations or virtual desktop infrastructure (VDI) environments to reduce exposure. 8. Review and harden RT application settings to minimize caching or sensitive data exposure where possible. 9. Conduct regular security audits of RT deployments focusing on data handling and session termination processes. 10. Develop incident response plans to address potential data exposure incidents related to this vulnerability.
