QNAP NAS is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input by the Proxy Server. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to perform unauthorized actions. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.
