CVE-2024-20277Network attack vector

Root command execution via insufficient input validation

Published Jan 17, 2024 · Updated Oct 23, 2024

Command injection in Cisco ThousandEyes Enterprise Agent Virtual Appliance 0.233 and earlier allows remote authenticated users to execute commands as root. The web-based management interface insufficiently validates input from crafted HTTP packets before the input reaches command execution; Cisco has not disclosed the specific handler or command sink. Exploitation requires high-privileged authentication and user interaction, and successful requests grant root-level command execution on the appliance.
