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 metacharactersin 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 [ 2 ] CAN-2004-1037 https://www.cve.org/CVERecord?id=CAN-2004-1037 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200411-33 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.
