Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
TOTOLINK X18 V9.1.0cu.2053_B20230309 was discovered to contain a command injection vulnerability via the agentName parameter in the setEasyMeshAgentCfg function.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

TOTOLINK X18 router firmware V9.1.0cu.2053_B20230309 contains a command injection vulnerability in the setEasyMeshAgentCfg function where the agentName parameter is not properly sanitized before being passed to system calls, allowing remote attackers to execute arbitrary OS commands.

MitigationApply vendor firmware patch when available; until then, restrict network access to the router's management interface to minimize exposure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the router model and firmware version
    Access the router's web administration interface and navigate to the System or Status page to view the firmware version. Alternatively, check the version via CLI if telnet/ssh access is available, or inspect the firmware binary if extracted from an update file.
    Affected if The firmware version is exactly 9.1.0cu.2053_b20230309 (or any version derived from this specific build).
  2. Locate the EasyMesh configuration settings
    In the router's web interface, look for settings related to EasyMesh, mesh networking, or Wi-Fi Easy Mesh. This is typically found under Wireless, Network, or Advanced settings. Note the exact navigation path varies by firmware version.
    Affected if The EasyMesh or mesh networking feature is enabled and configurable on the device.
  3. Verify access to the setEasyMeshAgentCfg function
    Attempt to access or inspect the web API endpoint that handles EasyMesh configuration. This may involve viewing the router's HTTP requests/responses, checking for a form or API call that includes an 'agentName' parameter in the setEasyMeshAgentCfg function.
    Affected if The router exposes an interface (web form or API) to configure EasyMesh mesh agent settings where an agentName parameter can be submitted.

You are affected if your TOTOLINK X18 router runs firmware version 9.1.0cu.2053_b20230309 and the EasyMesh feature is enabled, exposing the vulnerable setEasyMeshAgentCfg function with the unsanitized agentName parameter.
