The following security issues have been discovered in Bugzilla: * A CSRF vulnerability in process_bug.cgi affecting Bugzilla 4.4 only can lead to a bug being edited without the user consent. * A CSRF vulnerability in attachment.cgi can lead to an attachment being edited without the user consent. * Several unfiltered parameters when editing flagtypes can lead to XSS. * Due to an incomplete fix for CVE-2012-4189, some incorrectly filtered field values in tabular reports can lead to XSS. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Cross-Site Request Forgery Versions: 4.4rc1 to 4.4 Fixed In: 4.4.1 Description: When a user submits changes to a bug right after another user did, a midair collision page is displayed to inform the user about changes recently made. This page contains a token which can be used to validate the changes if the user decides to submit his changes anyway. A regression in Bugzilla 4.4 caused this token to be recreated if a crafted URL was given, even when no midair collision page was going to be displayed, allowing an attacker to bypass the token check and abuse a user to commit changes on his behalf.

Using a crafted URL, an attacker could force the token to be recreated, allowing him to bypass the token check and abuse a user to commit changes on his behalf.
