The following security issues have been discovered in Bugzilla: * When viewing tabular or graphical reports as well as new charts, an XSS vulnerability is possible in debug mode. * The User.offer_account_by_email WebService method lets you create a new user account even if the active authentication method forbids users to create an account. * A CSRF vulnerability in post_bug.cgi and in attachment.cgi could lead to the creation of unwanted bug reports and attachments. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Cross-Site Scripting Versions: 2.17.1 to 3.4.12, 3.5.1 to 3.6.6, 3.7.1 to 4.0.2, 4.1.1 to 4.1.3 Fixed In: 3.4.13, 3.6.7, 4.0.3, 4.2rc1 Description: Tabular and graphical reports, as well as new charts have a debug mode which displays raw data as plain text. This text is not correctly escaped and a crafted URL could use this vulnerability to inject code leading to XSS. References: https://bugzilla.mozilla.org/show_bug.cgi?id=697699 CVE Number: CVE-2011-3657 Class: Unauthorized Account Creation Versions: 2.23.3 to 3.4.12, 3.5.1 to 3.6.6, 3.7.1 to 4.0.2, 4.1.1 to 4.1.3 Fixed In: 3.4.13, 3.6.7, 4.0.3, 4.2rc1 Description: The User.offer_account_by_email WebService method ignores the user_can_create_account setting of the authentication method and generates an email with a token in it which the user can use to create an account. Depending on the authentication method being active, this could allow the user to log in using this account. Installations where the createemailregexp parameter is empty are not vulnerable to this issue. References: https://bugzilla.mozilla.org/show_bug.cgi?id=711714 CVE Number: CVE-2011-3667 Class: Cross-Site Request Forgery Versions: 2.0 to 3.4.12, 3.5.1 to 3.6.6, 3.7.1 to 4.0.2, 4.1.1 to 4.1.3 Fixed In: 4.2rc1 Description: The creation of bug reports and of attachments is not protected by a token and so they can be created without the consent of a user if the relevant code is embedded in an HTML page and the user visits this page. This behavior was intentional to let third-party applications submit new bug reports and attachments easily. But as this behavior can be abused by a malicious user, it has been decided to block submissions with no valid token starting from version 4.2rc1. Older branches are not patched to not break these third-party applications after the upgrade.
