Cisco warns of critical flaws allowing Nexus switch takeover

Cisco released security advisories for five critical vulnerabilities in its NX-OS data center network operating system that could be exploited to run arbitrary code with root privileges on Nexus switches.

If remote code execution cannot be achieved, an attacker could exploit the vulnerabilities to crash processes and force the vulnerable device to reload, resulting in a denial-of-service condition.

The issues affect the NX-API, Next Generation OAM (NGOAM), and MPLS OAM features in Nexus 3000 and Nexus 9000 Series switches.
