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 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.

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 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."

Cross-site request forgery (CSRF) vulnerability in editversions.cgi in Bugzilla before 2.22.1 and 2.23.x before 2.23.3 allows user-assisted remote attackers to create, modify, or delete arbitrary bug reports via a crafted URL.

SQL injection vulnerability in whineatnews.pl in Bugzilla 2.17 through 2.18.4 and 2.20 allows remote authenticated users with administrative privileges to execute arbitrary SQL commands via the whinedays parameter, as accessible from editparams.cgi.

The Flag::validate and Flag::modify functions in Bugzilla 2.17.1 to 2.18.1 and 2.19.1 to 2.19.3 do not verify that the flag ID is appropriate for the given bug or attachment ID, which allows users to change flags on arbitrary bugs and obtain a bug summary via process_bug.cgi.

Bugzilla 2.17.x, 2.18 before 2.18.2, 2.19.x, and 2.20 before 2.20rc1 inserts a bug into the database before it is marked private, which introduces a race condition and allows attackers to access information about the bug via buglist.cgi before MySQL replication is complete.

post_bug.cgi in Bugzilla 2.10 through 2.18, 2.19.1, and 2.19.2 allows remote authenticated users to "enter bugs into products that are closed for bug entry" by modifying the URL to specify the name of the product.

Bugzilla 2.17.1 through 2.18, 2.19.1, and 2.19.2, when a user is prompted to log in while attempting to view a chart, displays the password in the URL, which may allow local users to gain sensitive information from web logs or browser history.

Cross-site scripting (XSS) vulnerability in Bugzilla before 2.18, including 2.16.x before 2.16.11, allows remote attackers to inject arbitrary HTML and web script via forced error messages, as demonstrated using the action parameter.

process_bug.cgi in Bugzilla 2.9 through 2.18rc2 and 2.19 from CVS does not check edit permissions on the keywords field, which allows remote authenticated users to modify the keywords in a bug via the keywordaction parameter.

show_bug.cgi in Bugzilla 2.17.1 through 2.18rc2 and 2.19 from CVS, when using the insidergroup feature and exporting a bug to XML, shows comments and attachment summaries which are marked as private, which allows remote attackers to gain sensitive information.

Bugzilla 2.17.1 through 2.18rc2 and 2.19 from cvs, when using the insidergroup feature, does not sufficiently protect private attachments when there are changes to the metadata, such as filename, description, MIME type, or review flags, which allows remote authenticated users to obtain sensitive information when (1) viewing the bug activity log or (2) receiving bug change notification mails.

SQL injection vulnerability in collectstats.pl for Bugzilla 2.16.3 and earlier allows remote authenticated users with editproducts privileges to execute arbitrary SQL via the product name.

SQL injection vulnerability in Bugzilla 2.16.3 and earlier, and 2.17.1 through 2.17.4, allows remote authenticated users with editkeywords privileges to execute arbitrary SQL via the id parameter to editkeywords.cgi.

editproducts.cgi in Bugzilla 2.16.3 and earlier, when usebuggroups is enabled, does not properly remove group add privileges from a group that is being deleted, which allows users with those privileges to perform unauthorized additions to the next group that is assigned with the original group ID.

votes.cgi in Bugzilla 2.16.3 and earlier, and 2.17.1 through 2.17.4, allows remote attackers to read a user's voting page when that user has voted on a restricted bug, which allows remote attackers to read potentially sensitive voting information by modifying the who parameter.
