Authenticated OS Command Injection in AVTECH CloudSetup.cgi
CVE-2016-15047 is an authenticated OS command injection vulnerability affecting AVTECH devices that expose the CloudSetup.cgi management endpoint. The flaw is in the handling of the exefile parameter, which is passed to an underlying system command execution path without proper validation, sanitization, or whitelisting. An authenticated attacker able to access CloudSetup.cgi can supply crafted exefile input to inject and execute arbitrary operating system commands. The available reporting indicates commands execute with root privileges on the device. The vendor has not defined a precise affected version range, but archived third-party disclosure material suggests the issue was remediated in early 2017.

exefile values, and rotate any credentials stored on or accessible from the device if compromise is suspected. Where code or compensating controls are available, enforce strict validation and sanitization or allowlisting of the exefile parameter.Remediation
Patch, then assume compromise.
