Background ========== DokuWiki is a wiki targeted at developer teams, workgroups and small companies. It does not use a database backend. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/dokuwiki < 20060309d >= 20060309d Description =========== "rgod" discovered that DokuWiki doesn't sanitize the X-FORWARDED-FOR HTTP header, allowing the injection of arbitrary contents - such as PHP commands - into a file. Additionally, the accessory scripts installed in the "bin" DokuWiki directory are vulnerable to directory traversal attacks, allowing to copy and execute the previously injected code. Impact ====== A remote attacker may execute arbitrary PHP (and thus probably system) commands with the permissions of the user running the process serving DokuWiki pages. Workaround ========== Disable remote access to the "bin" subdirectory of the DokuWiki installation. Remove the directory if you don't use the scripts in there. Resolution ========== All DokuWiki users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/dokuwiki-20060309d" References ========== [ 1 ] CVE-2006-4674 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4674 [ 2 ] CVE-2006-4675 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4675 [ 3 ] CVE-2006-4679 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4679 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200609-10.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.
