Some serious security issues were discovered in Bugzilla and have been fixed in 3.4.10 and 3.6.4.

See http://www.bugzilla.org/security/3.2.9/ for details.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities were discovered in Bugzilla, a web-based bug tracking system.

  - CVE-2010-4572     By inserting particular strings into certain URLs, it     was possible to inject both headers and content to any     browser.

  - CVE-2010-4567, CVE-2011-0048     Bugzilla has a 'URL' field that can contain several     types of URL, including 'javascript:' and 'data:' URLs.
    However, it does not make 'javascript:' and 'data:' URLs     into clickable links, to protect against cross-site     scripting attacks or other attacks. It was possible to     bypass this protection by adding spaces into the URL in     places that Bugzilla did not expect them. Also,     'javascript:' and'data:' links were always shown as     clickable to logged-out users.

  - CVE-2010-4568     It was possible for a user to gain unauthorized access     to any Bugzilla account in a very short amount of time     (short enough that the attack is highly effective).

  - CVE-2011-0046     Various pages were vulnerable to Cross-Site Request     Forgery attacks. Most of these issues are not as serious     as previous CSRF vulnerabilities.

  - CVE-2011-2978     When a user changes his email address, Bugzilla trusts a     user-modifiable field for obtaining the current e-mail     address to send a confirmation message to. If an     attacker has access to the session of another user (for     example, if that user left their browser window open in     a public place), the attacker could alter this field to     cause the email-change notification to go to their own     address. This means that the user would not be notified     that his account had its email address changed by the     attacker.

  - CVE-2011-2381     For flagmails only, attachment descriptions with a     newline in them could lead to the injection of crafted     headers in email notifications when an attachment flag     is edited.

  - CVE-2011-2379     Bugzilla uses an alternate host for attachments when     viewing them in raw format to prevent cross-site     scripting attacks. This alternate host is now also used     when viewing patches in 'Raw Unified' mode because     Internet Explorer 8 and older, and Safari before 5.0.6     do content sniffing, which could lead to the execution     of malicious code.

  - CVE-2011-2380, CVE-2011-2979     Normally, a group name is confidential and is only     visible to members of the group, and to non-members if     the group is used in bugs. By crafting the URL when     creating or editing a bug, it was possible to guess if a     group existed or not, even for groups which weren't used     in bugs and so which were supposed to remain     confidential.

The remote host is affected by the vulnerability described in GLSA-201110-03 (Bugzilla: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Bugzilla. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could conduct cross-site scripting attacks, conduct       script insertion and spoofing attacks, hijack the authentication of       arbitrary users, inject arbitrary HTTP headers, obtain access to       arbitrary accounts, disclose the existence of confidential groups and its       names, or inject arbitrary e-mail headers.
    A local attacker could disclose the contents of temporarfy files for       uploaded attachments.
  Workaround :

    There is no known workaround at this time.

The remote web server is hosting Bugzilla, a web-based bug tracking application.

Versions of Bugzilla 3.2.x earlier than 3.2.10, 3.4.x earlier than 3.4.10, and 3.6.x earlier than 3.6.4 are potentially affected by multiple vulnerabilities :

  - A weakness could allow a user to gain unauthorized access to another Bugzilla account.

  - A weakness in the Perl CGI.pm module allows injecting HTTP headers and content to users via several pages.

  - It is possible to insert harmful 'javascript:' or 'data:' URLs into Bugzilla's 'URL' field which in some cases Buzilla will make clickable.

  - Various pages lack protection against cross-site request forgeries.
