system, file management, contact manager, mail client and many other

In detail, the following flaws were determined during a quick source
code review for the modules Projects, Contacts, Helpdesk, Notes, Search
During the validation the php.ini setting "magic_quotes_gpc" was
PHProjekt using an internal a CSRF protection (see function
check_csrftoken() in lib/lib.inc.php).
By calling this function the return value is always true. Due to incorrect
output validation in many modules, such as Mail or Filemanager,
Cross Site Request Forgery is possible.
Finally, the Cross Site Request Forgery vulnerability also affect the
summary page, which is PHProjekt's index page.
There may be other modules which are affected, but they have not been
