This flaw can be exploited to overwrite critical system files, inject malicious code into web application directories, or deface the web application. The existence of a public exploit (EDB-52584) on Exploit-DB significantly increases the likelihood of exploitation. Successful exploitation could lead to remote code execution or denial of service.
