Summary
RT is an open source, enterprise-grade issue and ticket tracking system. Versions 5.0.0 and 6.0.0 and above, prior to both 5.0.10 and 6.0.3 contain a Cross-Site Scripting (XSS) vulnerability where uploaded content is served inline rather than as an attachment. An authenticated user who can upload content can include JavaScript in the upload that will execute in the browser session of any RT user who later views or downloads it.
Risk Assessment
The risk involves the execution of arbitrary scripts in the context of other RT users' browsers, potentially leading to data theft or session hijacking.
Recommendation
It is recommended to upgrade RT to version 5.0.10 or 6.0.3, depending on the major version in use.
