description

WAVLINK WL-WN530BE1-A firmware V251117 is affected by a command-injection flaw in protocol.csp request handling. A remote attacker may execute commands by sending crafted input to the affected interface; the evidence indicates network reachability but does not specify an authentication requirement.

mitigation

Restrict access to the device's management interface to trusted administrative networks and prevent exposure to the internet. Monitor vendor updates and install a corrected firmware release when one is published.
