Multiple buffer overflows in the Cisco Discovery Protocol (CDP) implementation in Cisco NX-OS on Nexus 7000 devices 4.x and 5.x before 5.2(4) and 6.x before 6.1(1), Nexus 5000 and 5500 devices 4.x and 5.x before 5.1(3)N1(1), Nexus 4000 devices before 4.1(2)E1(1h), Nexus 3000 devices 5.x before 5.0(3)U3(1), Nexus 1000V devices 4.x before 4.2(1)SV1(5.1), MDS 9000 devices 4.x and 5.x before 5.2(4), Unified Computing System (UCS) 6100 and 6200 devices before 2.0(2m), and Connected Grid Router (CGR) 1000 devices before CG4(1) allow remote attackers to execute arbitrary code via malformed CDP packets, aka Bug IDs CSCtu10630, CSCtu10551, CSCtu10550, CSCtw56581, CSCtu10548, CSCtu10544, and CSCuf61275.

Security readout for executives and security teams

This flaw affects several Cisco network and compute platforms that process Cisco Discovery Protocol traffic. Malformed CDP packets can trigger buffer overflows and may allow arbitrary code execution on vulnerable devices. The source bundle lists fixed software versions, but does not provide CVSS scoring or evidence of active exploitation. Exposure is most likely in organizations still running the affected Cisco Nexus, MDS, UCS, or CGR versions listed in the CVE. The bundle does not state internet exposure; it ties the issue to devices processing malformed CDP packets. Treat this as a high-priority legacy infrastructure risk. It affects network platforms that can be operationally critical, and the stated impact is arbitrary code execution. Focus on finding remaining vulnerable versions and moving them to Cisco-fixed releases. Mitigation focus: Inventory Cisco Nexus, MDS, UCS, and CGR platforms in scope.; Upgrade to the fixed versions listed in the CVE or Cisco advisory.; Prioritize unsupported or legacy 4.x, 5.x, and early 6.x deployments..
