Abstract
The prevention of impersonation attacks based on hijacked common gateway interface (CGI) session IDs is disclosed. In accordance with one embodiment, a secured communication channel is formed between a server and a client using an initial transport layer security (TLS) key. Additionally, an authenticated CGI session is formed over the secured communication channel based on an initial CGI session identifier (ID). Further, the initial CGI session ID and the initial TLS key are combined into a pair. Next, incoming data that includes an incoming CGI session ID is received via a secured communication channel. An incoming TLS key of the secured communication channel that carries the incoming CGI session ID is then retrieved. Based on the retrieved incoming TLS key, the incoming data is permitted to execute on the server when the incoming TLS key matches the initial TLS key of the pair.
