Cisco has released patches for a dozen critical vulnerabilities, according to SecurityWeek. The flaws could enable unauthorized access, information leaks, privilege escalation, denial-of-service attacks, and remote code execution.
BleepingComputer reports that five of the critical issues are in NX-OS, Cisco's data center network operating system. These could be exploited to run arbitrary code with root privileges on Nexus switches, effectively allowing a full switch takeover.
The two reports agree on the severity and potential impact, but differ in scope: SecurityWeek frames the advisory set as a dozen critical vulnerabilities across Cisco products, while BleepingComputer focuses specifically on the five NX-OS flaws affecting Nexus switches. Both point to urgent patching.
