CVE-2024-22366 — Active debug code exists in Yamaha wireless LAN access point devices

Medium CVSS 6.8

Active debug code exists in Yamaha wireless LAN access point devices. If a logged-in user who knows how to use the debug function accesses the device's management page, this function can be enabled by performing specific operations. As a result, an arbitrary OS command may be executed and/or configuration settings of the device may be altered. Affected products and versions are as follows: WLX222 firmware Rev.24.00.03 and earlier, WLX413 firmware Rev.22.00.05 and earlier, WLX212 firmware Rev.21.00.12 and earlier, WLX313 firmware Rev.18.00.12 and earlier, and WLX202 firmware Rev.16.00.18 and earlier.

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.
