Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Description
MVPower CCTV DVR models, including TV-7104HE 1.8.4 115215B9 and TV7108HE, contain a web shell that is accessible via a /shell URI. A remote unauthenticated attacker can execute arbitrary operating system commands as root. This vulnerability has also been referred to as the "JAWS webserver RCE" because of the easily identifying HTTP response server field. Other firmware versions, at least from 2014 through 2019, can be affected. This was exploited in the wild in 2017 through 2022.

Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2016-20016 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
