Multiple cross-site request forgery (CSRF) vulnerabilities in the check_csrftoken function in lib/lib.inc.php in PHProjekt 5.2.0, when magic_quotes_gpc is disabled, allow remote attackers to perform unauthorized actions as an arbitrary user via the (1) Projects, (2) Contacts, (3) Helpdesk, (4) Notes, (5) Search, (6) Mail, or (7) Filemanager module; the (9) summary page; or unspecified other files.

Unrestricted file upload vulnerability in PHProjekt 5.2.0, when magic_quotes_gpc is disabled, allows remote authenticated users to upload and execute arbitrary PHP code via a file with an executable extension, which is then accessed by the (1) calendar or (2) file management module, or possibly unspecified other files.

Multiple PHP remote file inclusion vulnerabilities in the Content Management module ("Content manager") for PHProjekt 0.6.1, when register_globals is enabled, allow remote attackers to execute arbitrary PHP code via the path_pre parameter in (1) cm_lib.inc.php, (2) doc/br.edithelp.php, (3) doc/de.edithelp.php, (4) doc/ct.edithelp.php, (5) userrating.php, and (6) listing.php, a different set of vectors than CVE-2006-4204. NOTE: a third-party researcher has disputed the impact of the cm_lib.inc.php vector, stating that it is limited to local file inclusion. CVE analysis as of 20060905 concurs, although use of ftp URLs is also possible. The remaining five vectors have also been disputed by the same third party, stating that the path_pre variable is initialized before it is used

filemanager_forms.php in PHProjekt 3.1 and 3.1a allows remote attackers to execute arbitrary PHP code by specifying the URL to the code in the lib_path parameter.

PHProjekt before 2.4a allows remote attackers to perform actions as other PHProjekt users by modifying the ID number in an HTTP request to PHProjekt CGI programs.
