"Multiple vulnerabilities have been discovered in Request Tracker, an
extensible trouble-ticket tracking system. The Common Vulnerabilities
and Exposures project identifies the following problems :

  - CVE-2012-4733
    A user with the ModifyTicket right can bypass the
    DeleteTicket right or any custom life cycle transition
    rights and thus modify ticket data without
    authorization.

  - CVE-2013-3368
    The rt command line tool uses semi-predictable temporary
    files. A malicious user can use this flaw to overwrite
    files with permissions of the user running the rt
    command line tool.

  - CVE-2013-3369
    A malicious user who is allowed to see administration
    pages can run arbitrary Mason components (without
    control of arguments), which may have negative
    side-effects.

  - CVE-2013-3370
    Request Tracker allows direct requests to private
    callback components, which could be used to exploit a
    Request Tracker extension or a local callback which uses
    the arguments passed to it insecurely.

  - CVE-2013-3371
    Request Tracker is vulnerable to cross-site scripting
    attacks via attachment filenames.

  - CVE-2013-3372
    Dominic Hargreaves discovered that Request Tracker is
    vulnerable to an HTTP header injection limited to the
    value of the Content-Disposition header.

  - CVE-2013-3373
    Request Tracker is vulnerable to a MIME header injection
    in outgoing email generated by Request Tracker.

  Request Tracker stock templates are resolved by this update. But any
  custom email templates should be updated to ensure that values
  interpolated into mail headers do not contain newlines.

  - CVE-2013-3374
    Request Tracker is vulnerable to limited session re-use
    when using the file-based session store,
    Apache::Session::File. However Request Tracker's default
    session configuration only uses Apache::Session::File
    when configured for Oracle databases.

This version of Request Tracker includes a database content upgrade.
If you are using a dbconfig-managed database, you will be offered the
choice of applying this automatically. Otherwise see the explanation
in /usr/share/doc/request-tracker4/NEWS.Debian.gz for the manual steps
to perform.

Please note that if you run request-tracker4 under the Apache web
server, you must stop and start Apache manually. The 'restart'
mechanism is not recommended, especially when using mod_perl or any
form of persistent Perl process such as FastCGI or SpeedyCGI."

"Thomas Sibley reports :

We discovered a number of security vulnerabilities which affect both
RT 3.8.x and RT 4.0.x. We are releasing RT versions 3.8.17 and 4.0.13
to resolve these vulnerabilities, as well as patches which apply atop
all released versions of 3.8 and 4.0.

The vulnerabilities addressed by 3.8.17, 4.0.13, and the below patches
include the following :

RT 4.0.0 and above are vulnerable to a limited privilege escalation
leading to unauthorized modification of ticket data. The DeleteTicket
right and any custom life cycle transition rights may be bypassed by
any user with ModifyTicket. This vulnerability is assigned
CVE-2012-4733.

RT 3.8.0 and above include a version of bin/rt that uses
semi-predictable names when creating tempfiles. This could possibly be
exploited by a malicious user to overwrite files with permissions of
the user running bin/rt. This vulnerability is assigned CVE-2013-3368.

RT 3.8.0 and above allow calling of arbitrary Mason components
(without control of arguments) for users who can see administration
pages. This could be used by a malicious user to run private
components which may have negative side-effects. This vulnerability is
assigned CVE-2013-3369.

RT 3.8.0 and above allow direct requests to private callback
components. Though no callback components ship with RT, this could be
used to exploit an extension or local callback which uses the
arguments passed to it insecurely. This vulnerability is assigned
CVE-2013-3370.

RT 3.8.3 and above are vulnerable to cross-site scripting (XSS) via
attachment filenames. The vector is difficult to exploit due to
parsing requirements. Additionally, RT 4.0.0 and above are vulnerable
to XSS via maliciously-crafted 'URLs' in ticket content when RT's
'MakeClicky' feature is configured. Although not believed to be
exploitable in the stock configuration, a patch is also included for
RTIR 2.6.x to add bulletproofing. These vulnerabilities are assigned
CVE-2013-3371.

RT 3.8.0 and above are vulnerable to an HTTP header injection limited
to the value of the Content-Disposition header. Injection of other
arbitrary response headers is not possible. Some (especially older)
browsers may allow multiple Content-Disposition values which could
lead to XSS. Newer browsers contain security measures to prevent this.
Thank you to Dominic Hargreaves for reporting this vulnerability. This
vulnerability is assigned CVE-2013-3372.

RT 3.8.0 and above are vulnerable to a MIME header injection in
outgoing email generated by RT. The vectors via RT's stock templates
are resolved by this patchset, but any custom email templates should
be updated to ensure that values interpolated into mail headers do not
contain newlines. This vulnerability is assigned CVE-2013-3373.

RT 3.8.0 and above are vulnerable to limited session re-use when using
the file-based session store, Apache::Session::File. RT's default
session configuration only uses Apache::Session::File for Oracle. RT
instances using Oracle may be locally configured to use the
database-backed Apache::Session::Oracle, in which case sessions are
never re-used. The extent of session re-use is limited to information
leaks of certain user preferences and caches, such as queue names
available for ticket creation. Thank you to Jenny Martin for reporting
the problem that lead to discovery of this vulnerability. This
vulnerability is assigned CVE-2013-3374."

Solutions Request Tracker (RT) running on the remote web server is
version 3.8.x prior to 3.8.17 or version 4.x prior to 4.0.13. It is,
therefore, potentially affected by the following vulnerabilities :

  - A flaw exists that allows a remote, authenticated
    attacker with 'ModifyTicket' privileges to gain access
    to 'DeleteTicket' privileges, allowing tickets to be
    deleted without proper authorization. (CVE-2012-4733)

  - A flaw exists where the 'rt' command-line tool uses
    predictable temporary files. This allows a local
    attacker, using a symlink, to overwrite arbitrary
    files. (CVE-2013-3368)

  - A flaw exists that allows a remote, authenticated
    attacker who has permissions to view the administration
    pages to call arbitrary Mason components without the
    control of arguments (CVE-2013-3369)

  - A flaw exists where the application does not restrict
    direct requests to private callback components.
    (CVE-2013-3370)

  - A cross-site scripting vulnerability exists related to
    attachment file names that allows a remote attacker to
    inject arbitrary script or HTML. (CVE-2013-3371)

  - An unspecified flaw exists that allows a remote attacker
    to inject multiple Content-Disposition HTTP headers and
    possibly conduct cross-site scripting attacks.
    (CVE-2013-3372)

  - A flaw exists in the email templates that allows a
    remote attacker to inject MIME headers in email
    generated by the application. (CVE-2013-3373)

  - An information disclosure vulnerability exists due to
    the re-use of the Apache::Session::File session store.
    (CVE-2013-3374)

  - A flaw exists due to improper validation of URLs in
    tickets when the 'MakeClicky' component is enabled,
    which allows cross-site scripting attacks. Note this
    flaw only affects the RT 4.x branch. (CVE-2013-5587)

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