description

WAVLINK WN551X3-A devices running firmware M51X3_V251020-WO-182e965 are affected by command injection in DNS-resolution processing. A remote attacker may be able to run commands on the device by supplying manipulated input to the affected handler; the advisory does not establish whether authentication is required.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Isolate affected devices from untrusted networks and restrict access to device services to trusted administrators and networks. Monitor WAVLINK for a corrected firmware release and apply it promptly; no fixed version is recorded.
