Name of the Vulnerable Software and Affected Versions SolarWinds N-Central version 12.3.0.670

Description An issue was discovered in the SSH component of SolarWinds N-Central, where it does not restrict the communication channel to intended endpoints. This allows an attacker to leverage an SSH feature, specifically port forwarding with a temporary key pair, to access network services on the 127.0.0.1 interface. This feature was originally intended only for user-to-agent communication.

Recommendations For SolarWinds N-Central version 12.3.0.670, consider restricting access to the SSH component until a patch is available. As a temporary workaround, disabling the port forwarding feature with temporary key pairs may help minimize the risk of exploitation.
