Detailed vulnerability description
The vulnerability allows an attacker to execute arbitrary code on the target server.
The vulnerability exists due to a boundary error when a large host header is sent in a HTTP request to the IDAL HTTP server. An unauthenticated attacker can submit a Host header value of 2047 bytes or more to overflow the buffer and overwrite the SEH address, which can then be leveraged to execute attacker-controlled code on the server.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
