Best Practical Solutions RT 3.x before 3.8.9rc2 and 4.x before 4.0.0rc4 uses the MD5 algorithm for password hashes, which makes it easier for context-dependent attackers to determine cleartext passwords via a brute-force attack on the database.

Best Practical Solutions RT before 3.8.9 does not perform certain redirect actions upon a login, which allows physically proximate attackers to obtain credentials by resubmitting the login form via the back button of a web browser on an unattended workstation after an RT logout.

Scrips_Overlay.pm in Best Practical Solutions RT before 3.8.9 does not properly restrict access to a TicketObj in a Scrip after a CurrentUser change, which allows remote authenticated users to obtain sensitive information via unspecified vectors, as demonstrated by custom-field value information, related to SQL logging.

Best Practical Solutions RT 3.8.0 through 3.8.9 and 4.0.0rc through 4.0.0rc7, when the CustomFieldValuesSources (aka external custom field) option is enabled, allows remote authenticated users to execute arbitrary code via unspecified vectors, as demonstrated by a cross-site request forgery (CSRF) attack.

Multiple SQL injection vulnerabilities in Best Practical Solutions RT 2.0.0 through 3.6.10, 3.8.0 through 3.8.9, and 4.0.0rc through 4.0.0rc7 allow remote authenticated users to execute arbitrary SQL commands via unspecified vectors, as demonstrated by reading data.

Best Practical Solutions RT 3.0.0 through 3.6.10, 3.8.0 through 3.8.9, and 4.0.0rc through 4.0.0rc7 allows remote authenticated users to obtain sensitive information by using the search interface, as demonstrated by retrieving encrypted passwords.

Directory traversal vulnerability in Best Practical Solutions RT 3.2.0 through 3.6.10, 3.8.0 through 3.8.9, and 4.0.0rc through 4.0.0rc7 allows remote attackers to read arbitrary files via a crafted HTTP request.

Multiple cross-site scripting (XSS) vulnerabilities in Best Practical Solutions RT 2.0.0 through 3.6.10, 3.8.0 through 3.8.9, and 4.0.0rc through 4.0.0rc7 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Best Practical Solutions RT 3.6.0 through 3.6.10 and 3.8.0 through 3.8.8 allows remote attackers to trick users into sending credentials to an arbitrary server via unspecified vectors.

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.

Multiple cross-site scripting (XSS) vulnerabilities in Best Practical Solutions RT 3.x before 3.8.12 and 4.x before 4.0.6 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Best Practical Solutions RT 3.x before 3.8.12 and 4.x before 4.0.6 allows remote authenticated users to read (1) hashes of former passwords and (2) ticket correspondence history by leveraging access to a privileged account.

Multiple cross-site request forgery (CSRF) vulnerabilities in Best Practical Solutions RT before 3.8.12 and 4.x before 4.0.6 allow remote attackers to hijack the authentication of arbitrary users.

Best Practical Solutions RT 3.6.x, 3.7.x, and 3.8.x before 3.8.12 and 4.x before 4.0.6, when the VERPPrefix and VERPDomain options are enabled, allows remote attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2011-5092 and CVE-2011-5093.

Best Practical Solutions RT 3.x before 3.8.12 and 4.x before 4.0.6 does not properly disable groups, which allows remote authenticated users to bypass intended access restrictions in opportunistic circumstances by leveraging a group membership.

SQL injection vulnerability in Best Practical Solutions RT 2.x and 3.x before 3.8.12 and 4.x before 4.0.6 allows remote authenticated users to execute arbitrary SQL commands by leveraging access to a privileged account.

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.

Best Practical Solutions RT 4.x before 4.0.6 does not properly implement the DisallowExecuteCode option, which allows remote authenticated users to bypass intended access restrictions and execute arbitrary code by leveraging access to a privileged account, a different vulnerability than CVE-2011-4458 and CVE-2011-5092.

Multiple cross-site scripting (XSS) vulnerabilities in the topic administration page in the Extension::MobileUI extension before 1.02 for Best Practical Solutions RT 3.8.x and in Best Practical Solutions RT before 4.0.6 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The Authen::ExternalAuth extension before 0.11 for Best Practical Solutions RT allows remote attackers to obtain a logged-in session via unspecified vectors related to the "URL of a RSS feed of the user."
