CVE-2019-1732: Cisco NX-OS Software Remote Package Manager Command Injection Vulnerability

A vulnerability in the Remote Package Manager (RPM) subsystem of Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to leverage a time-of-check, time-of-use (TOCTOU) race condition to corrupt local variables, which could lead to arbitrary command injection. The vulnerability is due to the lack of a proper locking mechanism on critical variables that need to stay static until used. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a set of RPM-related CLI commands. A successful exploit could allow the attacker to perform arbitrary command injection. The attacker would need administrator credentials for the targeted device.

Security readout for executives and security teams

CVE-2019-1732 affects Cisco NX-OS Software. An attacker who already has administrator credentials on the device could abuse RPM-related CLI behavior to inject commands. This is not a remote unauthenticated issue, but compromise of network infrastructure admin access can still create serious business impact. Organizations running Cisco NX-OS Software on affected devices may be exposed. The provided sources do not specify exact affected versions or platforms. Practical exposure depends on whether attackers can obtain administrator credentials and local CLI access to the targeted device. Prioritize remediation through the network infrastructure maintenance process, especially for high-value switches or environments with weak privileged-access controls. This is not KEV-listed and requires admin credentials, so urgency is moderate unless credential compromise is suspected. Mitigation focus: Review Cisco advisory for affected and fixed NX-OS software details.; Apply Cisco-recommended software updates or workarounds where applicable.; Restrict administrator access to trusted operators and management networks..

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
