CVE-2024-20306

Root command execution via crafted UTD CLI input

Published Mar 27, 2024 · Updated Aug 16, 2024

Command injection in the UTD configuration CLI in Cisco IOS XE Software allows local users with level 15 privileges to execute commands as root. The CLI accepts a crafted configuration command without sufficient input validation, allowing attacker-controlled command content to reach the underlying host. Exposure requires an affected release on a device that supports the utd engine standard unified-policy command.
