The Bugzilla::Search::build_subselect function in Bugzilla 2.x and 3.x before 3.6.13 and 3.7.x and 4.0.x before 4.0.10 generates different error messages for invalid product queries depending on whether a product exists, which allows remote attackers to discover private product names by using debug mode for a query.

Multiple vulnerablilities was identified and fixed in bugzilla :

The get_attachment_link function in Template.pm in Bugzilla 2.x and 3.x before 3.6.10, 3.7.x and 4.0.x before 4.0.7, 4.1.x and 4.2.x before 4.2.2, and 4.3.x before 4.3.2 does not check whether an attachment is private before presenting the attachment description within a public comment, which allows remote attackers to obtain sensitive description information by reading a comment (CVE-2012-1969).

Auth/Verify/LDAP.pm in Bugzilla 2.x and 3.x before 3.6.11, 3.7.x and 4.0.x before 4.0.8, 4.1.x and 4.2.x before 4.2.3, and 4.3.x before 4.3.3 does not restrict the characters in a username, which might allow remote attackers to inject data into an LDAP directory via a crafted login attempt (CVE-2012-3981).

Cross-site scripting (XSS) vulnerability in Bugzilla 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1, allows remote attackers to inject arbitrary web script or HTML via a field value that is not properly handled during construction of a tabular report, as demonstrated by the Version field (CVE-2012-4189).

Bugzilla/Attachment.pm in attachment.cgi in Bugzilla 2.x and 3.x before 3.6.12, 3.7.x and 4.0.x before 4.0.9, 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1 allows remote attackers to read attachment descriptions from private bugs via an obsolete=1 insert action (CVE-2012-4197).

The User.get method in Bugzilla/WebService/User.pm in Bugzilla 3.7.x and 4.0.x before 4.0.9, 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1 has a different outcome for a groups request depending on whether a group exists, which allows remote authenticated users to discover private group names by observing whether a call throws an error (CVE-2012-4198).

template/en/default/bug/field-events.js.tmpl in Bugzilla 3.x before 3.6.12, 3.7.x and 4.0.x before 4.0.9, 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1 generates JavaScript function calls containing private product names or private component names in certain circumstances involving custom-field visibility control, which allows remote attackers to obtain sensitive information by reading HTML source code (CVE-2012-4199).

Cross-site scripting (XSS) vulnerability in the Flash component infrastructure in YUI 2.8.0 through 2.9.0, as used in Bugzilla 3.7.x and 4.0.x before 4.0.9, 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1, allows remote attackers to inject arbitrary web script or HTML via vectors related to swfstore.swf, a similar issue to CVE-2010-4209 (CVE-2012-5883).

Cross-site scripting (XSS) vulnerability in show_bug.cgi in Bugzilla before 3.6.13, 3.7.x and 4.0.x before 4.0.10, 4.1.x and 4.2.x before 4.2.5, and 4.3.x and 4.4.x before 4.4rc2 allows remote attackers to inject arbitrary web script or HTML via the id parameter in conjunction with an invalid value of the format parameter (CVE-2013-0785).

The Bugzilla::Search::build_subselect function in Bugzilla 2.x and 3.x before 3.6.13 and 3.7.x and 4.0.x before 4.0.10 generates different error messages for invalid product queries depending on whether a product exists, which allows remote attackers to discover private product names by using debug mode for a query (CVE-2013-0786).

The updated packages have upgraded to the 4.2.5 version which is not vulnerable to these issues

According to its banner, the version of Bugzilla installed on the remote host is affected by multiple vulnerabilities :

  - A cross-site scripting vulnerability exists due to a     flaw in the validation of the 'id' parameter upon     submission of the 'show_bug.cgi' script.  An attacker     can leverage this to inject arbitrary HTML and script     code in a user's browser to be executed within the     security context of the affected site.  Note that this     affects versions 2.0 to 3.6.12, 3.7.1 to 4.0.9,     4.1.1 to 4.2.4, and 4.3.1 to 4.4rc1.
    (CVE-2013-0785)

  - An information leak issue exists when running a query     in debug mode.  This can lead to the display of the     SQL query used to collect the data.  Confidential     information could be leaked in the SQL query that is     displayed.	Note that this affects versions 2.17.1 to     3.6.12, and 3.7.1 to 4.0.9.  (CVE-2013-0786)

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

A Bugzilla Security Advisory reports:Cross-Site Scripting When viewing a single bug report, which is the default, the bug ID is validated and rejected if it is invalid. But when viewing several bug reports at once, which is specified by the format=multiple parameter, invalid bug IDs can go through and are sanitized in the HTML page itself. But when an invalid page format is passed to the CGI script, the wrong HTML page is called and data are not correctly sanitized, which can lead to XSS. Information Leak When running a query in debug mode, the generated SQL query used to collect the data is displayed. The way this SQL query is built permits the user to determine if some confidential field value (such as a product name) exists. This problem only affects Bugzilla 4.0.9 and older. Newer releases are not affected by this issue.
