Authenticated OS Command Injection in AVTECH Cloud Setup
CVE-2016-15047 is an authenticated operating-system command-injection vulnerability affecting AVTECH IP cameras, NVRs, and DVRs that expose the cloud setup management endpoint. The endpoint passes the exefile parameter to system command execution without adequate validation or whitelisting. An authenticated attacker can submit crafted input to execute arbitrary commands as root and fully compromise the device. An affected firmware version range has not been established.
What it means and what to do now: patch path, interim mitigations, and the assume-compromise checklist.
What an attacker gets, and what they’ve been doing with it.
Successful exploitation permits arbitrary operating-system command execution as root and full control of the affected device. Credential theft, data exfiltration, and lateral movement may be possible depending on stored credentials, deployment configuration, and connectivity to internal systems. C0XMO includes exploitation support for this vulnerability in its HTTP scanning toolkit.
If you can’t patch tonight, do this now.
Disable the CloudSetup.cgi endpoint if unnecessary, or restrict access to trusted management systems. FortiGuard IPS provides a signature covering exploitation of CVE-2016-15047; deploy applicable inspection controls as an additional protective measure.
Patch, then assume compromise.
Update affected AVTECH devices to current vendor-supported firmware and confirm that the command-injection flaw is addressed. An archived SEARCH-LAB disclosure suggests remediation occurred in early 2017, but no specific fixed version or affected version range is identified. The underlying software correction requires validating and sanitizing the exefile input before command execution.
