"According to its self-reported version number, the Best Practical
Solutions Request Tracker (RT) running on the remote web server is
version 3.x prior to 3.8.15 or version 4.x prior to 4.0.8. It is,
therefore, potentially affected by the following vulnerabilities :

  - Users can inject arbitrary headers into outgoing email
    provided they have ModifySelf or AdminUser privileges.
    A remote attacker could exploit this to gain sensitive
    information or conduct phishing attacks. (CVE-2012-4730)

  - Any privileged user can create articles in any class due
    to the application failing to properly verify user
    access rights. (CVE-2012-4731)

  - A cross-site request forgery vulnerability exists that
    allows a remote attacker to hijack the authentication
    of users for requests that toggle ticket bookmarks.
    (CVE-2012-4732)

  - A warning bypass vulnerability exists that allows a
    'confused deputy' attack during the handling of a
    specially crafted link. (CVE-2012-4734)

  - A vulnerability exists that allows an attacker to send
    arbitrary arguments to the command line for the GnuPG
    client (if GnuPG is enabled), which could result in the
    creation of arbitrary files with the permissions of the
    web server. (CVE-2012-4884)

  - Multiple vulnerabilities exist related to the improper
    signing or encryption of messages using GnuPG when GnuPG
    is enabled. (CVE-2012-6578, CVE-2012-6579,
    CVE-2012-6580, CVE-2012-6581)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");

"BestPractical report :

All versions of RT are vulnerable to an email header injection attack.
Users with ModifySelf or AdminUser can cause RT to add arbitrary
headers or content to outgoing mail. Depending on the scrips that are
configured, this may be be leveraged for information leakage or
phishing.

RT 4.0.0 and above and RTFM 2.0.0 and above contain a vulnerability
due to lack of proper rights checking, allowing any privileged user to
create Articles in any class.

All versions of RT with cross-site-request forgery (CSRF) protection
(RT 3.8.12 and above, RT 4.0.6 and above, and any instances running
the security patches released 2012-05-22) contain a vulnerability
which incorrectly allows though CSRF requests which toggle ticket
bookmarks.

All versions of RT are vulnerable to a confused deputy attack on the
user. While not strictly a CSRF attack, users who are not logged in
who are tricked into following a malicious link may, after supplying
their credentials, be subject to an attack which leverages their
credentials to modify arbitrary state. While users who were logged in
would have observed the CSRF protection page, users who were not
logged in receive no such warning due to the intervening login
process. RT has been extended to notify users of pending actions
during the login process.

RT 3.8.0 and above are susceptible to a number of vulnerabilities
concerning improper signing or encryption of messages using GnuPG; if
GnuPG is not enabled, none of the following affect you."
