Invicti identified that code execution via WebDAV. Invicti successfully uploaded a file via PUT method and then renamed this file via MOVE method. When requesting the file, code is executed in the context of the web server. At the end of the attack, Invicti tried to delete the file.

An attacker can execute malicious code by abusing the Code Execution via WebDAV vulnerability on the server.

Remove write permissions from this directory or disable WebDAV if it's not being used.

This vulnerability is not difficult to leverage. Successful exploitation requires knowledge of the programming language, access to or the ability to produce source code for use in such attacks, and minimal attack skills.
