4.2rc2 and 4.0.4 Security Advisory
Wednesday, February 22nd, 2012
Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issue has been discovered
* A CSRF vulnerability in the implementation of the XML-RPC API
when running under mod_perl could be used to make changes to
bugs or execute some admin tasks without the victim's knowledge.
All affected installations are encouraged to upgrade as soon as
Class: Cross-Site Request Forgery
Versions: 4.0.2 to 4.0.4, 4.1.1 to 4.2rc2
Fixed In: 4.0.5, 4.2
Description: Due to a lack of validation of the enctype form
attribute when making POST requests to xmlrpc.cgi,
a possible CSRF vulnerability was discovered. If a user
visits an HTML page with some malicious HTML code in it,
an attacker could make changes to a remote Bugzilla installation
on behalf of the victim's account by using the XML-RPC API
on a site running mod_perl. Sites running under mod_cgi
are not affected. Also the user would have had to be
already logged in to the target site for the vulnerability
CVE Number: CVE-2012-0453
The fix for this issue is included in the 4.0.5 and 4.2 releases.
Upgrading to a release with the relevant fix will protect your
installation from possible exploits of this issue.

individual security vulnerability, there is a patch available for
the issue at the "References" URL for the vulnerability.
