Detailsinfo

A vulnerability was found in Cms.tut.su CMS Chainuk up to 1.2 (Content Management System). It has been rated as critical. Affected by this issue is an unknown code of the file admin/admin_menu.php. The manipulation of the argument id=../menu.csv with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Multiple directory traversal vulnerabilities in CMS Chainuk 1.2 and earlier allow remote attackers to include and execute arbitrary local files via a .. (dot dot) in (1) the menu parameter to admin/admin_menu.php, and the id parameter to (2) index.php and (3) admin/admin_edit.php; and (4) delete arbitrary local files via a .. (dot dot) in the id parameter to admin/admin_delete.php. NOTE: vector 2 can be leveraged for static code injection by sending a crafted menu parameter to admin/admin_menu.php, and then sending an id=../menu.csv request to index.php.
