Summary

The SNMP module in Cisco NX-OS versions 7.0(3)N1(1) and earlier on Nexus 5000 and 6000 devices allows remote attackers to exploit variations in error messages. This inconsistency permits attackers to identify existing VLANs through systematic queries, thereby compromising network integrity and security.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
