The login form in Bugzilla 2.x, 3.x, 4.x before 4.4.3, and 4.5.x before 4.5.3 does not properly handle a correctly authenticated but unintended login attempt, which makes it easier for remote authenticated users to obtain sensitive information by arranging for a victim to login to the attacker's account and then submit a vulnerability report, related to a "login CSRF" issue.
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 processbug.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.
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 the quips feature in Mozilla Bugzilla 2.10 through 2.17 allows remote attackers to inject arbitrary web script or HTML via the "show all quips" page.
Bugzilla before 3.0.11, 3.2.x before 3.2.6, 3.4.x before 3.4.5, and 3.5.x before 3.5.3 does not block access to files and directories that are used by custom installations, which allows remote attackers to obtain sensitive information via requests for (1) CVS/, (2) contrib/, (3) docs/en/xml/, (4) t/, or (5) old-params.txt.
Cross-site request forgery (CSRF) vulnerability in attachment.cgi in Bugzilla 2.x, 3.x, and 4.0.x before 4.0.11; 4.1.x and 4.2.x before 4.2.7; and 4.3.x and 4.4.x before 4.4.1 allows remote attackers to hijack the authentication of arbitrary users for requests that commit an attachment change via an update action.
Bugzilla 2.x and 3.x through 3.6.11, 3.7.x and 4.0.x before 4.0.8, 4.1.x and 4.2.x before 4.2.3, and 4.3.x before 4.3.3 stores potentially sensitive information under the web root with insufficient access control, which allows remote attackers to read (1) template (aka .tmpl) files, (2) other custom extension files under extensions/, or (3) custom documentation files under docs/ via a direct request.
Multiple cross-site scripting (XSS) vulnerabilities in editflagtypes.cgi in Bugzilla 2.x, 3.x, and 4.0.x before 4.0.11; 4.1.x and 4.2.x before 4.2.7; and 4.3.x and 4.4.x before 4.4.1 allow remote attackers to inject arbitrary web script or HTML via the (1) id or (2) sortkey parameter.
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.
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.
describecomponents.cgi in Bugzilla 2.17.3 and 2.17.4 does not properly verify group membership when bug entry groups are used, which allows remote attackers to list component descriptions for otherwise restricted products.
showbug.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.
processbug.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.
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.
Unknown vulnerability in (1) duplicates.cgi and (2) buglist.cgi in Bugzilla 2.16.x before 2.16.6, 2.18 before 2.18rc1, when configured to hide products, allows remote attackers to view hidden products.
Bugzilla 2.17.5 through 2.17.7 embeds the password in an image URL, which could allow local users to view the password in the web server log files.
DBI in Bugzilla 2.17.1 through 2.17.7 displays the database password in an error message when the SQL server is not running, which could allow remote attackers to gain sensitive information.
Unknown vulnerability in the administrative controls in Bugzilla 2.17.1 through 2.17.7 allows users with "grant membership" privileges to grant memberships to groups that the user does not control.
Multiple cross-site scripting (XSS) vulnerabilities in (1) editcomponents.cgi, (2) editgroups.cgi, (3) editmilestones.cgi, (4) editproducts.cgi, (5) editusers.cgi, and (6) editversions.cgi in Bugzilla 2.16.x before 2.16.6, and 2.18 before 2.18rc1, allow remote attackers to execute arbitrary JavaScript as other users via a URL parameter.
SQL injection vulnerability in editusers.cgi in Bugzilla 2.16.x before 2.16.6, and 2.18 before 2.18rc1, allows remote attackers with privileges to grant membership to any group to execute arbitrary SQL.
The shadow database feature (syncshadowdb) in Bugzilla 2.9 through 2.16.10 allows local users to overwrite arbitrary files via a symlink attack on temporary files.
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.
postbug.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 2.10 through 2.18, 2.19.1, and 2.19.2 displays a different error message depending on whether a product exists or not, which allows remote attackers to determine hidden products.
emailin.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.
Bugzilla 2.14 through 2.22.7; 3.0.x, 3.1.x, and 3.2.x before 3.2.10; 3.4.x before 3.4.10; 3.6.x before 3.6.4; and 4.0.x before 4.0rc2 does not properly generate random values for cookies and tokens, which allows remote attackers to obtain access to arbitrary accounts via unspecified vectors, related to an insufficient number of calls to the srand function.
