Critical CVSS 9.8

There are multiple unauthorized remote command execution vulnerabilities in the H3C ER2200G2, ERG2-450W, ERG2-1200W, ERG2-1350W, NR1200W series routers before ERG2AW-MNW100-R1117; H3C ER3100G2, ER3200G2, ER3260G2, ER5100G2, ER5200G2, ER6300G2, ER8300G2, ER8300G2-X series routers before ERHMG2-MNW100-R1126; GR3200, GR5200, GR8300 and other series routers before MiniGR1B0V100R018L50; GR-1800AX before MiniGRW1B0V100R009L50; GR-3000AX before SWBRW1A0V100R007L50; and GR-5400AX before SWBRW1B0V100R009L50. Attackers can bypass authentication by including specially crafted text in the request URL or message header, and then inject arbitrary malicious commands into some fields related to ACL access control list and user group functions and execute to obtain the highest ROOT privileges of remote devices, thereby completely taking over the remote target devices.

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.
