The MobileUI (aka RT-Extension-MobileUI) extension before 1.04 in Request Tracker (RT) 4.0.0 before 4.0.13, when using the file-based session store (Apache::Session::File) and certain authentication extensions, allows remote attackers to reuse unauthorized sessions and obtain user preferences and caches via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the MobileUI (aka RT-Extension-MobileUI) extension before 1.04 in Request Tracker (RT) 4.0.0 before 4.0.13 allows remote attackers to inject arbitrary web script or HTML via the name of an attached file.

Best Practical Solutions RT 3.8.x before 3.8.15 and 4.0.x before 4.0.8, when GnuPG is enabled, does not ensure that the UI labels unencrypted messages as unencrypted, which might make it easier for remote attackers to spoof details of a message's origin or interfere with encryption-policy auditing via an e-mail message to a queue's address.

Best Practical Solutions RT 3.8.x before 3.8.15 and 4.0.x before 4.0.8, when GnuPG is enabled, allows remote attackers to configure encryption or signing for certain outbound e-mail, and possibly cause a denial of service (loss of e-mail readability), via an e-mail message to a queue's address.

Best Practical Solutions RT 3.8.x before 3.8.15 and 4.0.x before 4.0.8, when GnuPG is enabled with a "Sign by default" queue configuration, uses a queue's key for signing, which might allow remote attackers to spoof messages by leveraging the lack of authentication semantics.

Best Practical Solutions RT 3.8.x before 3.8.15 and 4.0.x before 4.0.8, when GnuPG is enabled, allows remote attackers to bypass intended restrictions on reading keys in the product's keyring, and trigger outbound e-mail messages signed by an arbitrary stored secret key, by leveraging a UI e-mail signing privilege.

SQL injection vulnerability in Approvals/ in Request Tracker (RT) 4.0.10 and earlier allows remote attackers to execute arbitrary SQL commands via the ShowPending parameter. NOTE: the vendor disputes this issue, stating "We were unable to replicate it, and the individual that reported it retracted their report," and "we had verified that the claimed exploit did not function according to the author's claims.

Multiple cross-site scripting (XSS) vulnerabilities in the topic administration page in the RTFM extension 2.0.4 through 2.4.3 for Best Practical Solutions RT allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

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.
