A command injection vulnerability in Cisco Enterprise NFV Infrastructure Software allows an authenticated local attacker to execute arbitrary commands as root via a crafted configuration file.

Vulnerability

A command injection vulnerability exists in Cisco Enterprise NFV Infrastructure Software (NFVIS) due to insufficient input validation of a configuration file accessible to local shell users. Affected versions include all releases prior to the fixed version. The vulnerability is triggered when a local user with shell access executes a configuration file containing malicious input.

Exploitation

An attacker must have authenticated local shell access to the NFVIS system. The attacker can craft a configuration file with malicious input and execute it, leading to command injection. No additional privileges are required beyond local shell access.

Impact

Successful exploitation allows the attacker to execute arbitrary commands on the underlying operating system as root, resulting in full compromise of the affected device.

Mitigation

Cisco has released free software updates to address this vulnerability. Users should upgrade to the fixed version as specified in Cisco Security Advisory cisco-sa-20190703-nfvis-commandinj [1]. No workarounds are available.
