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 underlying system command execution without proper validation or whitelisting. An authenticated attacker able to access CloudSetup.cgi can supply crafted input via exefile to execute arbitrary operating system commands on the device. The available reporting indicates commands execute with root privileges, resulting in full compromise of the affected device. The archived SEARCH-LAB disclosure suggests the issue was remediated in early 2017, but AVTECH has not published a defined affected version range.

exefile values. Where compensating controls are available, apply input validation or filtering for the exefile parameter and segment affected devices from sensitive internal systems.Remediation
Patch, then assume compromise.
exefile has been corrected before returning devices to service. If possible, remove or replace devices that cannot be confirmed patched.Exploits
