4.4rc1, 4.2.4, 4.0.9, and 3.6.12 Security AdvisoryTuesday Feb 19th, 2013
Summary ======= Bugzilla is a Web-based bug-tracking system used by a large number of software projects. The following security issues have 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 possible. 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.

Newer releases are not affected by this issue.
