This bypasses the stricter checks used by the regular upload path, allowing attackers to upload server\u2011side executable files such as .phtml, .php5, or .htaccess. If such a file is executed by the web server, the attacker can run arbitrary code on the host, compromising confidentiality, integrity, or availability of the affected system.

It is not included in CISA\u2019s Known Exploited Vulnerabilities catalog. The attack can be performed remotely through the WebDAV upload interface; an authenticated or unauthenticated client that can send uploads may trigger the flaw. In deployments lacking Apache LocationMatch protection, a malicious file can be executed immediately, giving an attacker full control over the host.
