Description

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. An attacker could exploit this vulnerability by connecting to the Snort 3 control channel socket as a local user. A successful exploit could allow the attacker to execute arbitrary commands as well as read and write Snort 3 process memory.
