Background ========== TWiki is a Web-based groupware tool based around the concept of wiki pages that can be edited by anybody with a Web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/twiki < 20040902 >= 20040902 Description =========== The TWiki search function, which uses a shell command executed via the Perl backtick operator, does not properly escape shell metacharacters in the user-provided search string. Impact ====== An attacker can insert malicious commands into a search request, allowing the execution of arbitrary commands with the privileges of the user running TWiki (usually the Web server user). Workaround ========== There is no known workaround at this time. Resolution ========== All TWiki users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/twiki-20040902" References ========== [ 1 ] TWiki Security Alert http://twiki.org/cgi-bin/view/Codev/SecurityAlertExecuteCommandsWithSearch [ 2 ] CAN-2004-1037 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1037 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200411-33.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
