Request Tracker (RT) 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2 allows remote attackers to obtain sensitive information about cross-site request forgery (CSRF) verification tokens via a crafted URL.

Cross-site scripting (XSS) vulnerability in Request Tracker (RT) 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2, when the AlwaysDownloadAttachments config setting is not in use, allows remote attackers to inject arbitrary web script or HTML via a file upload with an unspecified content type.

The dashboard subscription interface in Request Tracker (RT) 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2 might allow remote authenticated users with certain privileges to execute arbitrary code via a crafted saved search name.

Request Tracker (RT) 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2 does not use a constant-time comparison algorithm for secrets, which makes it easier for remote attackers to obtain sensitive user password information via a timing side-channel attack.

The email gateway in RT (aka Request Tracker) 3.0.0 through 4.x before 4.0.23 and 4.2.x before 4.2.10 allows remote attackers to cause a denial of service (CPU and disk consumption) via a crafted email.

RT (aka Request Tracker) 3.8.8 through 4.x before 4.0.23 and 4.2.x before 4.2.10 allows remote attackers to obtain sensitive RSS feed URLs and ticket data via unspecified vectors.

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.
