CVE-2023-32350 — Teltonika-Networks Rut200 Firmware security vulnerability

High CVSS 8.8

Versions 00.07.00 through 00.07.03 of Teltonika’s RUT router firmware contain an operating system (OS) command injection vulnerability in a Lua service. An attacker could exploit a parameter in the vulnerable function that calls a user-provided package name by instead providing a package with a malicious name that contains an OS command injection payload.

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.
