4.4rc1, 4.2.4, 4.0.9, and 3.6.12 Security Advisory

Tuesday, Feb 19th, 2013

Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issue has been discovered
in Bugzilla:

* When viewing a bug report, a bug ID containing random code is not
correctly sanitized in the HTML page if the specified page format
is invalid. This can lead to XSS.

* When running a query in debug mode, it is possible to determine if
a given confidential field value (such as a product name) exists.
Bugzilla 4.1 and newer are not affected by this issue.

All affected installations are encouraged to upgrade as soon as

Vulnerability Details

Class:       Cross-Site Scripting
Versions:    2.0 to 3.6.12, 3.7.1 to 4.0.9, 4.1.1 to 4.2.4, 4.3.1 to 4.4rc1
Fixed In:    3.6.13, 4.0.10, 4.2.5, 4.4rc2
Description: 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.
