CVE-2021-27449Network attack vector

Authenticated command execution through undisclosed web input

Published Dec 21, 2021 · Updated Sep 17, 2024

Command injection in Mesa Laboratories AmegaView 3.0 and earlier allows remote authenticated users to execute commands on the web server. CISA has not published the affected web handler, parameter, or input-processing operation that permits shell metacharacters to reach command execution. Low-privileged authenticated access is sufficient, and successful exploitation grants control over data and service operation on the server.
