This vulnerability allows remote attackers to write arbitrary files on affected installations of CentOS Web Panel cwp-e17.0.9.8.923. Authentication is not required to exploit this vulnerability. The specific flaw exists within ajax_mod_security.php. When parsing the archivo parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-9722.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
