CVE-2024-20411

Root code execution via insufficient Bash restrictions

Published Aug 28, 2024 · Updated Aug 30, 2024

Code execution in Cisco NX-OS Software allows local users to execute arbitrary code as root through the Bash shell. The command-execution path applies insufficient security restrictions to a specially crafted operating-system command issued from Bash. Exploitation requires valid device access and Bash-shell privileges; the feature is disabled by default, although a configured Bash login shell remains sufficient.
