Stored XSS via crafted URLs in HTML ticket content in Request Tracker

RT's automatic link creation for URLs in HTML ticket content does not HTML-escape the URL it places in the link. A URL crafted to break out of the link's address can add a script that runs when the ticket history is displayed, with no further action by the viewer. Anyone who can add HTML content to a ticket can plant it. That includes an unauthenticated sender of HTML email to any queue that grants CreateTicket or ReplyToTicket to Everyone, which is routine for a queue that accepts mail from the public. The script runs in the session of any user who views the ticket, and can act in RT with that user's authority. This issue was fixed in version 5.0.11 and 6.0.4

RT: Request Tracker 3.5.HEAD allows remote attackers to obtain sensitive information via the Rows parameter in Dist/Display.html, which reveals the installation path in an error message.

Cross-site scripting (XSS) vulnerability in the web interface for Request Tracker (RT) 1.0 through 1.0.7 allows remote attackers to execute script via message bodies.

Deprecated 3DES cryptographic algorithm used by Request Tracker in emails encrypted with S/MIME

Vulnerability in Best Practical Solutions, LLC's Request Tracker prior to v5.0.8, where the Triple DES (3DES) cryptographic algorithm is used to protect emails sent with S/MIME encryption.

Information exposure vulnerability in Request Tracker (RT)

Information exposure vulnerability in RT software affecting version 4.4.1.
