Some vulnerabilities have been reported in RT, which can be exploited by malicious people to conduct spoofing attacks, cross-site scripting attacks, and disclose potentially sensitive information and by malicious users to disclose potentially sensitive information, conduct SQL injection attacks, and compromise a vulnerable system.
1) An error within the "external custom field" feature can be exploited to inject and execute arbitrary code.
Successful exploitation requires that "CustomFieldValuesSources" is enabled (disabled by default).
Note: This vulnerability only affects version 3.8.0 and later and can also be exploited to via cross-site request forgery attacks.
2) Certain unspecified input is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting SQL code.
3) An unspecified error within the search interface can be exploited to disclose certain sensitive information (e.g. encrypted passwords).
Successful exploitation requires a privileged user account.
4) An unspecified error can be exploited to trick a user into sending authentication credentials to an untrusted 3rd party server.
5) Certain input is not properly verified before being used to access files. This can be exploited to access and disclose files outside of RT's root directory via directory traversal attacks.
Note: Certain servers (e.g. Apache, nginx) mitigate this attack.
6) Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Provided and/or discovered by: Reported by the vendor.
