Maximum-severity SonicWall SMA flaw is being exploited
Dark Reading reports that a maximum-severity server-side request forgery flaw in SonicWall SMA remote-access devices is under active attack. These appliances sit at the network edge and give staff and suppliers a route into internal systems, so one compromised unit can become a foothold behind the firewall. Exploitation has already started, which shortens the time between disclosure and intrusion. Organisations running SMA should first establish where the devices are deployed, including units managed by third parties. Apply the vendor's fixes or mitigations as soon as they are available and restrict management interfaces to trusted addresses. Review logs for unusual outbound requests and for new administrator accounts created since the flaw became known. If compromise cannot be ruled out, rotate the credentials and certificates the device handled, and treat the appliance as untrusted until it has been rebuilt. Brief the board on exposure now, so that an incident does not force the question later and the response is already agreed.
