3.0.4, 3.1.4, and 2.22.4 Security Advisory
Tuesday, Aug 12th, 2008Summary ======= Bugzilla is a Web-based bug-tracking system used by a large number of software projects. The following security issue has been discovered in Bugzilla: * Local files on the server can be attached to a bug (making them publicly visible) when importing bugs with --attach_path All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Directory Traversal Versions: 2.22.1 - 2.22.4, 2.23.3 and higher Description: When importing bugs using importxml.pl, the --attach_path option can be specified, pointing to the directory where attachments to import are stored. If the XML file being read by importxml.pl contains a malicious <data encoding="filename">../relative_path/to/local_file</data> node, the script follows this relative path and attaches the local file pointed by it to the bug, making the file public. The security fix makes sure the relative path is always ignored. Most Bugzilla installations will not be vulnerable, as they do not use --attach_path with importxml.pl. (In fact, most installations don't use importxml.pl at all.)
