An attacker can gain access to the application using HTTP PUT method.
The HTTP PUT method is normally used to upload data that is saved on the server at a user-supplied URL. If enabled, an attacker may be able to place arbitrary, and potentially malicious, content into the application. Depending on the server's configuration, this may lead to compromise of other users (by uploading client-executable scripts), compromise of the server (by uploading server-executable code), or other attacks.
PUT method have to be disabled.
