    descriptionMultiple 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.

    "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."

    descriptionThomas 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

    "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."

    "According to its self-reported version number, the Best Practical
    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.");
