Background ========== phpWebSite provides a complete web site content management system. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/phpwebsite < 0.10.0-r2 >= 0.10.0-r2 Description =========== NST discovered that, when submitting an announcement, uploaded files aren't correctly checked for malicious code. They also found out that phpWebSite is vulnerable to a path disclosure. Impact ====== A remote attacker can exploit this issue to upload files to a directory within the web root. By calling the uploaded script the attacker could then execute arbitrary PHP code with the rights of the web server. By passing specially crafted requests to the search module, remote attackers can also find out the full path of PHP scripts. Workaround ========== There is no known workaround at this time. Resolution ========== All phpWebSite users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/phpwebsite-0.10.0-r2" References ========== [ 1 ] Secunia Advisory SA14399 http://secunia.com/advisories/14399/ [ 2 ] phpWebSite announcement http://phpwebsite.appstate.edu/index.php?module=announce&ANN_id=922&ANN_user_op=view Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-04.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.
