TITLE

Cisco FXOS and NX-OS Input verification vulnerabilities in software

Trust: 0.8

sources: JVNDB: JVNDB-2020-002477

DESCRIPTION

A vulnerability in the Cisco Discovery Protocol feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code as root or cause a denial of service (DoS) condition on an affected device. The vulnerability exists because of insufficiently validated Cisco Discovery Protocol packet headers. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful exploit could allow the attacker to cause a buffer overflow that could allow the attacker to execute arbitrary code as root or cause a DoS condition on the affected device. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). Note: This vulnerability is different from the following Cisco FXOS and NX-OS Software Cisco Discovery Protocol vulnerabilities that Cisco announced on Feb. 5, 2020: Cisco FXOS, IOS XR, and NX-OS Software Cisco Discovery Protocol Denial of Service Vulnerability and Cisco NX-OS Software Cisco Discovery Protocol Remote Code Execution Vulnerability. Cisco FXOS and NX-OS The software contains an input verification vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. Cisco NX-OS Software and Cisco FXOS Software are both products of Cisco Corporation. Cisco NX-OS Software is a suite of data center-level operating system software for switches
