CVE-2017-9828 — Vivotek Network Camera Ib8369 Firmware security vulnerability

Critical CVSS 9.8

'/cgi-bin/admin/testserver.cgi' of the web service in most of the VIVOTEK Network Cameras is vulnerable to shell command injection, which allows remote attackers to execute any shell command as root via a crafted HTTP request. This vulnerability is already verified on VIVOTEK Network Camera IB8369/FD8164/FD816BA; most others have similar firmware that may be affected. An attack uses shell metacharacters in the senderemail parameter.

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.
