QNAP QTS Web devRequest Stack-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of QNAP QTS. Authentication is not required to exploit this vulnerability. The specific flaw exists within devRequest.cgi. When parsing the password parameter, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of root.
