Cisco fixes seven critical flaws in Nexus switches
Original: Seven critical CVEs across two product lines. None exploited yet. No workarounds exist. Here's the fast triage. NX-OS NG
Cisco's Nexus 3000 and 9000 series switches are affected by seven newly disclosed critical vulnerabilities across two product lines, including three CVSS 9.8 unauthenticated remote code execution flaws in NX-OS NGOAM (VXLAN OAM). None of the flaws have been exploited in the wild so far, and no workarounds are available, making prompt patching the only defence.
Why now: Security teams are rushing to triage seven unpatched, unauthenticated RCE-grade bugs in widely deployed data centre switches.
