Due to a firewall misconfiguration, Kerlink devices running KerOS prior to 5.12 incorrectly accept specially crafted UDP packets. This allows an attacker to bypass the firewall and access UDP-based services that would otherwise be protected.

The service wmp-agent of KerOS prior 5.12 does not properly validate so-called ‘magic URLs’ allowing an unauthenticated remote attacker to execute arbitrary OS commands as root when the service is reachable over network. Typically, the service is protected via local firewall.
