Descriptions

A improper limitation of a pathname to a restricted directory ('path traversal') in Fortinet FortiWeb versions 7.0.0 through 7.6.0 allows attacker to execute unauthorized code or commands via crafted requests.

This vulnerability allows remote attackers to create arbitrary XML schema files on affected installations of Fortinet FortiWeb. Authentication is required to exploit this vulnerability.
The specific flaw exists within the cgi_xmlprotection_xmlschemafile_post function. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create XML schema files in the context of root.
