-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0468 -- [Win][UNIX/Linux] Bugzilla - Multiple Security Vulnerabilities 9 May 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Bugzilla 3.1.3 and prior Bugzilla 3.0.3 and prior Bugzilla 2.22.3 and prior Bugzilla 2.20.5 and prior Publisher: Bugzilla Operating System: UNIX variants (UNIX, Linux, OSX) Windows Impact: Increased Privileges Cross-site Scripting Access: Remote/Unauthenticated CVE Names: CVE-2008-2103 CVE-2008-2104 CVE-2008-2105 Original Bulletin: http://www.bugzilla.org/security/2.20.5/ Revision History: May 9 2008: Added CVE numbers May 7 2008: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. This advisory covers three security issues that have recently been fixed in the Bugzilla code: * Users without the "canconfirm" privilege could enter a bug as NEW or ASSIGNED by using the XML-RPC interface. * When viewing several bugs at once, there was a Cross-Site Scripting hole. * The inbound email interface allowed you to set the Reporter via the text of the email, instead of just using the From header. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Unauthorized Bug Change Versions: 3.1.3 Description: Users normally need the "canconfirm" privilege to put bugs in the NEW or ASSIGNED state. However, users were being allowed to create bugs in the NEW or ASSIGNED state if they were creating the bug through the XML-RPC interface. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=415471 Class: Cross-Site Scripting Versions: 2.17.2 and higher Description: When using the "Format for Printing" view of a bug (or the "Long Format" of a bug list, which is the same thing), there was a cross-site scripting hole--arbitrary text from a particular URL parameter could be injected into the page without filtering. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=425665 Class: Account Impersonation (Minor) Versions: 2.23.4 and higher Description: By design, email_in.pl always believes the "From" header as the user making changes or uses that as the reporter of the bug. However, you could also specify the changer/reporter in the body of the email and override the "From" header, possibly bypassing some security checks set up by administrators against the "From" header. For most installations this is a minor or inconsequential issue, as the documentation of email_in.pl already explains that it does not do any user authentication (it just believes the "From" header), so installations using it should not have been expecting user account security (though they may have had checks against the "From" header--that is what makes this a security issue). Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=419188 Vulnerability Solutions ======================= The fixes for the security bugs mentioned in this advisory are included in the 3.0.4, 3.1.4, 2.22.4, and 2.20.6 releases.
