Components of PHProjekt: Group calendar, project management, time card system, file management, contact manager, mail client and many other modules. PHProjekt supports many protocols like ldap, xml/soap and webdav and is available for 38 languages and 9 databases." Description: The vendor has been informed that every authenticated user can upload any files, e.g., through the calendar or file management module. With this privilege it is possible to upload PHP files with arbitrary code, which can subsequently be instantly executed. This suggests a privilege escalation is possible. Solution: The vulnerabilities were reported on Dec 31 2006 and an update has been released on Mar 14 2007. ______________________________________________ ________________________________________________________________________ Credit: Bugs found by Alexios Fakos of n.runs AG. ________________________________________________________________________ References: p ________________________________________________________________________ Unaltered electronic reproduction of this advisory is permitted.
