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.

Exploitability Analysis:

This is a vulnerability exploitable with adjacent network access and requires the attacker to have access to either the broadcast or collision domain of the vulnerable software. Examples of local networks include local IP subnet, Bluetooth, IEEE 802.11, and local Ethernet segment.

Exploitability Complexity:

Specialized access conditions or extenuating circumstances do not exist. The following are examples: The affected product typically requires access to a wide range of systems and users, possibly anonymous an untrusted (e.g., Internet-facing web or mail server). The affected configuration is default or ubiquitous. The attack can be performed manually and requires little skill or additional information gathering. The 'race condition' is a lazy one (i.e., it is technically a race but easily winnable).


Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact:

There is total information disclosure, resulting in all system files being revealed. The attacker is able to read all of the system's data (memory, files, etc.).

Integrity Impact:

There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being compromised. The attacker is able to modify any files on the target system.

Availability Impact:

There is a total shutdown of the affected resource. The attacker can render the resource completely unavailable.
