CVE-2022-45045 — Xiongmaitech Mbd6304T security vulnerability

High CVSS 8.8

Multiple Xiongmai NVR devices, including MBD6304T V4.02.R11.00000117.10001.131900.00000 and NBD6808T-PL V4.02.R11.C7431119.12001.130000.00000, allow authenticated users to execute arbitrary commands as root, as exploited in the wild starting in approximately 2019. A remote and authenticated attacker, possibly using the default admin:tlJwpbo6 credentials, can connect to port 34567 and execute arbitrary operating system commands via a crafted JSON file during an upgrade request. Since at least 2021, Xiongmai has applied patches to prevent attackers from using this mechanism to execute telnetd.

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.
