A vulnerability in the control channel socket implementation of Open Source Snort 3 could allow an authenticated, local attacker with low privileges to execute arbitrary commands as the Snort 3 process user. This vulnerability is due to a lack of authentication when a local user connects to the Snort control channel socket.
