Cisco warns of critical flaws allowing Nexus switch takeover

Cisco released security advisories addressing five critical vulnerabilities in its NX-OS operating system, which powers Nexus data center switches. These flaws could be exploited by attackers to execute arbitrary code with root-level privileges on affected devices. The vulnerabilities represent a significant risk to enterprise and data center network infrastructure. Successful exploitation could result in full device takeover, enabling attackers to intercept, manipulate, or disrupt network traffic. Cisco has urged administrators to apply patches promptly. The advisories highlight ongoing security challenges in network operating systems used in critical environments.
