Bugzilla 2.17.1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2 generates different error messages depending on whether a product exists, which makes it easier for remote attackers to guess product names via unspecified use of the (1) Reports or (2) Duplicates page.

Search.pm in Bugzilla 2.19.1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2 allows remote attackers to determine the group memberships of arbitrary users via vectors involving the Search interface, boolean charts, and group-based pronouns.

Bugzilla 3.2 before 3.2 RC2, 3.0 before 3.0.6, 2.22 before 2.22.6, 2.20 before 2.20.7, and other versions after 2.17.4 allows remote authenticated users to bypass moderation to approve and disapprove quips via a direct request to quips.cgi with the action parameter set to "approve."

Cross-site request forgery (CSRF) vulnerability in Bugzilla 2.17 to 2.22.7, 3.0 before 3.0.7, 3.2 before 3.2.1, and 3.3 before 3.3.2 allows remote attackers to delete unused flag types via a link or IMG tag to editflagtypes.cgi.

Bugzilla 2.x before 2.22.7, 3.0 before 3.0.7, 3.2 before 3.2.1, and 3.3 before 3.3.2 allows remote authenticated users to conduct cross-site scripting (XSS) and related attacks by uploading HTML and JavaScript attachments that are rendered by web browsers.

Cross-site request forgery (CSRF) vulnerability in Bugzilla before 3.2 before 3.2.1, 3.3 before 3.3.2, and other versions before 3.2 allows remote attackers to perform bug updating activities as other users via a link or IMG tag to process_bug.cgi.

Cross-site request forgery (CSRF) vulnerability in Bugzilla 2.22 before 2.22.7, 3.0 before 3.0.7, 3.2 before 3.2.1, and 3.3 before 3.3.2 allows remote attackers to delete keywords and user preferences via a link or IMG tag to (1) editkeywords.cgi or (2) userprefs.cgi.

Cross-site scripting (XSS) vulnerability in Bugzilla 2.17.2 and later allows remote attackers to inject arbitrary web script or HTML via the id parameter to the "Format for Printing" view or "Long Format" bug list.

email_in.pl in Bugzilla 2.23.4, 3.0.x before 3.0.4, and 3.1.x before 3.1.4 allows remote authenticated users to more easily spoof the changer of a bug via a @reporter command in the body of an e-mail message, which overrides the e-mail address as normally obtained from the From e-mail header. NOTE: since From headers are easily spoofed, this only crosses privilege boundaries in environments that provide additional verification of e-mail addresses.

Cross-site scripting (XSS) vulnerability in enter_bug.cgi in Bugzilla 2.17.1 through 2.20.4, 2.22.x before 2.22.3, and 3.x before 3.0.1 allows remote attackers to inject arbitrary web script or HTML via the buildid field in the "guided form."
