Summary
by MITRE • 07/20/2026
RT is an open source, enterprise-grade issue and ticket tracking system. Versions 5.0.4 up to (but not including) 5.0.10, and 6.0.0 up to (but not including) 6.0.3 contain a reflected Cross-Site Scripting (XSS) vulnerability where an attacker who can induce an authenticated RT user to visit a crafted URL can execute arbitrary JavaScript in that user's browser session. This issue has been fixed in versions 5.0.10 and 6.0.3.

The RT (Request Tracker) system represents a critical enterprise-grade ticketing solution widely deployed across organizations for managing support requests, incident tracking, and workflow automation. This vulnerability affects versions within the 5.x and 6.x release lines, specifically targeting authenticated user sessions through reflected cross-site scripting mechanisms that exploit how the application processes user input in HTTP responses. The flaw manifests when an attacker crafts malicious URLs containing script payloads that get reflected back to the victim's browser through the RT application's response handling. This vulnerability operates under CWE-79 which categorizes cross-site scripting flaws as weaknesses in web applications where untrusted data is not properly sanitized before being rendered in web pages, making it particularly dangerous in enterprise environments where privileged users frequently interact with ticketing systems.
The technical exploitation of this reflected XSS vulnerability requires an attacker to successfully诱导 an authenticated RT user to click on a maliciously crafted URL that contains JavaScript code within parameters or query strings. When the victim's browser requests this specially crafted URL, the RT application processes the input and reflects the malicious script content back in the HTTP response without proper sanitization or encoding. The reflected nature of this vulnerability means the attack payload is not stored on the server but rather passed through the application's normal request processing flow, making it particularly stealthy and difficult to detect through traditional security monitoring approaches. The impact extends beyond simple script execution as authenticated users may have elevated privileges within RT systems, potentially allowing attackers to escalate their access or extract sensitive information from ticket records.
The operational consequences of this vulnerability can be severe for organizations relying on RT for critical support operations, particularly when considering that privileged users such as system administrators or help desk personnel are most likely targets. Attackers could leverage this vulnerability to steal session cookies, perform actions on behalf of authenticated users, access confidential ticket data, or even redirect victims to malicious domains that could further compromise the organization's security posture. The vulnerability affects enterprise environments where RT serves as a central hub for incident management, making it an attractive target for adversaries seeking persistent access to organizational support infrastructure. Organizations with large user bases may face significant risk if attackers successfully exploit this vulnerability across multiple authenticated sessions.
Mitigation strategies should focus on immediate patch application to versions 5.0.10 or 6.0.3 where the XSS vulnerability has been resolved through proper input sanitization and output encoding mechanisms. Security teams should implement comprehensive monitoring for suspicious URL patterns and user behavior that might indicate exploitation attempts, while also conducting thorough code reviews of all web application components that process external input. Network-level protections such as web application firewalls can provide additional defense-in-depth measures, though these should not replace proper patching. Organizations should also consider implementing strict content security policies to limit script execution capabilities within the RT environment, and establish incident response procedures specifically tailored to address potential XSS exploitation scenarios. The vulnerability demonstrates the importance of maintaining up-to-date software versions and implementing robust input validation practices as outlined in industry standards such as those referenced in the ATT&CK framework under web application attacks and credential access techniques.
