CVE-2019-1768: Cisco NX-OS Software Buffer Overflow and Command Injection Vulnerability

A vulnerability in the implementation of a specific CLI command for Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to cause a buffer overflow condition or perform command injection. This could allow the attacker to execute arbitrary commands with elevated privileges on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of arguments passed to a certain CLI command. An attacker could exploit this vulnerability by including malicious input as the argument of the affected CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. An attacker would need valid administrator credentials to exploit these vulnerabilities.

Security readout for executives and security teams

This Cisco NX-OS flaw lets someone who already has administrator access to an affected device abuse a CLI command to run commands as root on the device OS. It is not a remote unauthenticated break-in, but it can turn a compromised or misused admin account into full device control. Exposure is limited to Cisco NX-OS Software devices covered by the Cisco advisory. The bundle does not provide specific affected versions, so teams must compare deployed NX-OS releases against Cisco's advisory and inventory. Handle as a moderate-priority infrastructure hardening item. The flaw requires existing administrator access, but successful abuse can produce root-level control of network devices. Prioritize internet-adjacent, critical routing, data-center, and shared-admin environments. Mitigation focus: Review Cisco's advisory for affected releases and official fixed software guidance.; Upgrade or remediate NX-OS devices according to Cisco's published instructions.; Restrict administrator access to trusted management networks and approved personnel..

Improper Restriction of Operations within the Bounds of a Memory Buffer

Improper Restriction of Operations within the Bounds of a Memory Buffer represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
