Cisco Patches Actively Exploited Catalyst SD-WAN Zero-Day Allowing Unauthenticated Admin Access

Cisco has released patches for a zero-day vulnerability in Catalyst SD-WAN appliances that is being actively exploited. The flaw permits remote, unauthenticated attackers to gain administrative privileges on affected devices. This is a critical network infrastructure risk, as SD-WAN devices are often deployed at network edges, and exploitation could enable deep network compromise.
