Request Tracker (RT) 4.x before 4.0.13 does not properly enforce the DeleteTicket and "custom lifecycle transition" permission, which allows remote authenticated users with the ModifyTicket permission to delete tickets via unspecified vectors.

Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13 allows remote attackers to inject multiple Content-Disposition HTTP headers and possibly conduct cross-site scripting (XSS) attacks via unspecified vectors.

Cross-site scripting (XSS) vulnerability in Request Tracker (RT) 3.8.3 through 3.8.16 and 4.0.x before 4.0.13 allows remote attackers to inject arbitrary web script or HTML via the filename of an attachment.

bin/rt in Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13 allows local users to overwrite arbitrary files via a symlink attack on a temporary file with predictable name.

Unspecified vulnerability in Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13, when using the Apache::Session::File session store, allows remote attackers to obtain sensitive information (user preferences and caches) via unknown vectors, related to a "limited session re-use."

Argument injection vulnerability in Request Tracker (RT) 3.8.x before 3.8.15 and 4.0.x before 4.0.8 allows remote attackers to create arbitrary files via unspecified vectors related to the GnuPG client.

Request Tracker (RT) 3.8.x before 3.8.15 and 4.0.x before 4.0.8 allows remote attackers to conduct a "confused deputy" attack to bypass the CSRF warning protection mechanism and cause victims to "modify arbitrary state" via unknown vectors related to a crafted link.

Request Tracker (RT) 3.8.x before 3.8.15 and 4.0.x before 4.0.8 allows remote authenticated users with ModifySelf or AdminUser privileges to inject arbitrary email headers and conduct phishing attacks or obtain sensitive information via unknown vectors.

Best Practical Solutions RT 3.8.x before 3.8.12 and 4.x before 4.0.6 allows remote attackers to execute arbitrary code and gain privileges via unspecified vectors, a different vulnerability than CVE-2011-4458 and CVE-2011-5093.

The vulnerable-passwords script in Best Practical Solutions RT 3.x before 3.8.12 and 4.x before 4.0.6 does not update the password-hash algorithm for disabled user accounts, which makes it easier for context-dependent attackers to determine cleartext passwords, and possibly use these passwords after accounts are re-enabled, via a brute-force attack on the database. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-0009.
