CVE-2019-1783: Cisco NX-OS Software Command Injection Vulnerability

Security readout for executives and security teams

CVE-2019-1783 affects Cisco NX-OS Software. An attacker who already has administrator credentials on an affected device could abuse a CLI command argument to run operating-system commands as root. This is not described as remote unauthenticated access, but it can turn a compromised or malicious admin account into full underlying device control. Exposure is likely limited to Cisco NX-OS deployments where the affected software is present and an attacker can obtain or misuse valid administrator credentials. The bundle does not identify exact affected versions, so version exposure must be checked against Cisco’s advisory. Treat as a moderate-priority network infrastructure risk. It is gated by administrator credentials, but compromise of those credentials could give root-level control on affected NX-OS devices. Prioritize environments with broad admin access, weak credential controls, or high-value switching infrastructure. Mitigation focus: Review Cisco’s advisory for affected NX-OS releases and vendor-provided remediation.; Limit NX-OS administrator access to trusted personnel and controlled management paths.; Audit administrator accounts and remove unnecessary privileged access..
