Who should care

Organizations running RT (Request Tracker) versions 6.0.0-6.0.2 for IT service management, help desk operations, or issue tracking. System administrators responsible for RT deployments, security teams monitoring web application vulnerabilities, and developers maintaining RT integrations or customizations.

Technical summary

RT (Request Tracker) versions 6.0.0 through 6.0.2 contain a Cross-Site Request Forgery (CWE-352) vulnerability. The application fails to properly validate or require anti-CSRF tokens for state-changing requests, allowing an attacker to construct a malicious web page that submits forged requests to the RT instance. When a victim with an active RT session visits the attacker's page, the browser automatically includes session cookies, causing RT to execute the forged action with the victim's privileges. This can lead to unauthorized ticket modifications, configuration changes, or other administrative actions depending on the victim's permissions. The vulnerability requires user interaction (victim must visit malicious page) but no authentication bypass or privilege escalation on the attacker's part.

Defensive priority

HIGH

Recommended defensive actions

  • Upgrade RT to version 6.0.3 or later to remediate this vulnerability.
  • Review and audit recent state-changing actions in RT for unauthorized changes if running affected versions.
  • Implement additional CSRF protections at the web application firewall (WAF) or reverse proxy layer as a defense-in-depth measure.
  • Educate users about the risks of clicking untrusted links while authenticated to sensitive applications.
  • Monitor for suspicious cross-origin requests to RT endpoints that may indicate CSRF exploitation attempts.
