TITLE

Cisco Nexus 7000 Run on device Cisco NX-OS Service disruption in (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2015-003225

DESCRIPTION

Cisco NX-OS 5.2(5) on Nexus 7000 devices allows remote attackers to cause a denial of service (device crash) by sending a malformed LLDP packet on the local network, aka Bug ID CSCud89415. Cisco NX-OS software is a data center-level operating system that reflects modular design, resiliency, and maintainability. A security vulnerability exists in the processing of LLDP packets by the Cisco NX-OS. The remote user on the local network can send the customized LLDP packets to the LLDP-enabled target interface. This can cause the target device to crash. Cisco NX-OS Software for Nexus 7000 Series is prone to a remote denial-of-service vulnerability. An attacker can leverage this issue to cause an affected device to crash; denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCud89415
