CVE intelligence and bounded remediation

CVE-2016-20016 — MVPower CCTV DVR models, including TV-7104HE 1.8.4 115215B9 and TV7108HE, contain a web shell that is accessible via a /shell URI

Critical CVSS 9.8

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.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
