Bugzilla 2.x through 4.0.x before 4.0.15, 4.1.x and 4.2.x before 4.2.11, 4.3.x and 4.4.x before 4.4.6, and 4.5.x before 4.5.6 allows remote authenticated users to obtain sensitive private-comment information by leveraging a role as a flag recipient, related to Bug.pm, Flag.pm, and a mail template.
The confirmcreateaccount function in the account-creation feature in token.cgi in Bugzilla 2.x through 4.0.x before 4.0.15, 4.1.x and 4.2.x before 4.2.11, 4.3.x and 4.4.x before 4.4.6, and 4.5.x before 4.5.6 does not specify a scalar context for the realname parameter, which allows remote attackers to create accounts with unverified e-mail addresses by sending three realname values with realname=loginname as the second, as demonstrated by selecting an e-mail address with a domain name for which group privileges are automatically granted.
The response function in the JSONP endpoint in WebService/Server/JSONRPC.pm in jsonrpc.cgi in Bugzilla 3.x and 4.x before 4.0.14, 4.1.x and 4.2.x before 4.2.10, 4.3.x and 4.4.x before 4.4.5, and 4.5.x before 4.5.5 accepts certain long callback values and does not restrict the initial bytes of a JSONP response, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks, and obtain sensitive information, via a crafted OBJECT element with SWF content consistent with the bzcallback character set.
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 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.

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.
Multiple cross-site scripting (XSS) vulnerabilities in report.cgi in Bugzilla 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 a field value that is not properly handled during construction of a tabular report, as demonstrated by the (1) summary or (2) real name field. NOTE: this issue exists because of an incomplete fix for CVE-2012-4189.
Cross-site scripting (XSS) vulnerability in showbug.cgi in Bugzilla before 3.6.13, 3.7.x and 4.0.x before 4.0.10, 4.1.x and 4.2.x before 4.2.5, and 4.3.x and 4.4.x before 4.4rc2 allows remote attackers to inject arbitrary web script or HTML via the id parameter in conjunction with an invalid value of the format parameter.
The Bugzilla::Search::buildsubselect function in Bugzilla 2.x and 3.x before 3.6.13 and 3.7.x and 4.0.x before 4.0.10 generates different error messages for invalid product queries depending on whether a product exists, which allows remote attackers to discover private product names by using debug mode for a query.
Cross-site scripting (XSS) vulnerability in Bugzilla 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1, allows remote attackers to inject arbitrary web script or HTML via a field value that is not properly handled during construction of a tabular report, as demonstrated by the Version field.
Bugzilla/Attachment.pm in attachment.cgi in Bugzilla 2.x and 3.x before 3.6.12, 3.7.x and 4.0.x before 4.0.9, 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1 allows remote attackers to read attachment descriptions from private bugs via an obsolete=1 insert action.
The User.get method in Bugzilla/WebService/User.pm in Bugzilla 3.7.x and 4.0.x before 4.0.9, 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1 has a different outcome for a groups request depending on whether a group exists, which allows remote authenticated users to discover private group names by observing whether a call throws an error.
Bugzilla is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the Flash component infrastructure in YUI script. A remote attacker could exploit this vulnerability using attack vectors related to swfstore.swf to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
The User.get method in Bugzilla/WebService/User.pm in Bugzilla 4.3.2 allows remote attackers to obtain sensitive information about the saved searches of arbitrary users via an XMLRPC request or a JSONRPC request, a different vulnerability than CVE-2012-4198.
template/en/default/bug/field-events.js.tmpl in Bugzilla 3.x before 3.6.12, 3.7.x and 4.0.x before 4.0.9, 4.1.x and 4.2.x before 4.2.4, and 4.3.x and 4.4.x before 4.4rc1 generates JavaScript function calls containing private product names or private component names in certain circumstances involving custom-field visibility control, which allows remote attackers to obtain sensitive information by reading HTML source code.
Auth/Verify/LDAP.pm in Bugzilla 2.x and 3.x before 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 does not restrict the characters in a username, which might allow remote attackers to inject data into an LDAP directory via a crafted login attempt.
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.
The getattachmentlink function in Template.pm in Bugzilla 2.x and 3.x before 3.6.10, 3.7.x and 4.0.x before 4.0.7, 4.1.x and 4.2.x before 4.2.2, and 4.3.x before 4.3.2 does not check whether an attachment is private before presenting the attachment description within a public comment, which allows remote attackers to obtain sensitive description information by reading a comment.
Bugzilla 4.1.x and 4.2.x before 4.2.2 and 4.3.x before 4.3.2 uses bug-editor privileges instead of bugmail-recipient privileges during construction of HTML bugmail documents, which allows remote attackers to obtain sensitive description information by reading the tooltip portions of an HTML e-mail message.
Bugzilla 3.5.x and 3.6.x before 3.6.9, 3.7.x and 4.0.x before 4.0.6, and 4.1.x and 4.2.x before 4.2.1, when the inboundproxies option is enabled, does not properly validate the X-Forwarded-For HTTP header, which allows remote attackers to bypass the lockout policy via a series of authentication requests with (1) different IP address strings in this header or (2) a long string in this header.
template/en/default/list/list.js.tmpl in Bugzilla 2.x and 3.x before 3.6.9, 3.7.x and 4.0.x before 4.0.6, and 4.1.x and 4.2.x before 4.2.1 does not properly handle multiple logins, which allows remote attackers to conduct cross-site scripting (XSS) attacks and obtain sensitive bug information via a crafted web page.
Cross-site request forgery (CSRF) vulnerability in xmlrpc.cgi in Bugzilla 4.0.2 through 4.0.4 and 4.1.1 through 4.2rc2, when modperl is used, allows remote attackers to hijack the authentication of arbitrary users for requests that modify the product's installation via the XML-RPC API.
