Summary

Cisco NX-OS 7.1(1)N1(1) on Nexus 5500, 5600, and 6000 devices lacks proper validation of Protocol Data Units (PDUs) in SNMP packets. This security gap allows remote attackers to craft specially designed packets, leading to a denial of service by triggering an unexpected restart of the SNMP application. Such exploits can severely disrupt network operations, making it essential for organizations to apply the recommended patches and secure their systems.
