CVE-2020-3167

Authenticated command execution via crafted CLI arguments

Published Feb 26, 2020 · Updated Nov 15, 2024

Command injection in Cisco FXOS and UCS Manager Software allows local users to execute operating-system commands through the CLI. The CLI accepts crafted arguments to specific commands without sufficient input validation before invoking the underlying operating system. A valid local session is required; commands run as the logged-in user except on UCS 6400 Series Fabric Interconnects, where they run as root.
