CVE-2024-8806Network attack vector

Unauthenticated root code execution via command injection

Published Nov 22, 2024 · Updated Dec 3, 2024

Command injection in Cohesive Networks VNS3 before 6.2.8 and 6.6.0 through 6.6.6 allows remote attackers to execute code as root. The TCP port 8000 web service passes an improperly validated user-supplied string to a system call. Control-plane access to port 8000 is required; authentication is not, and successful injection runs arbitrary commands with root privileges.
