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
Tenda A18 v15.03.05.05 firmware has a stack overflow vulnerability located via the PPW parameter in the fromWizardHandle 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 · moderate confidence

Tenda A18 v15.03.05.05 firmware contains a stack overflow vulnerability in the fromWizardHandle function, exploitable through the PPW parameter. The lack of proper bounds checking on user input allows an attacker to overflow a stack-allocated buffer, potentially enabling arbitrary code execution with the privileges of the affected service.

MitigationUpdate to a patched firmware version when available; if no patch exists, restrict network access to the device's management interface or consider device replacement.

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 device model
    Access the device web interface or check the device label to confirm it is a Tenda A18 access point
    Affected if The device is not a Tenda A18 model
  2. Check the firmware version
    Log into the Tenda A18 web管理界面 and navigate to System Settings > Firmware Upgrade, or check the device status page to locate the firmware version information
    Affected if The firmware version is 15.03.05.05
  3. Verify the web management interface is accessible
    Attempt to access the device's web interface via its IP address (typically 192.168.0.1 or 192.168.1.1) using a browser
    Affected if The web interface is accessible and responds to requests
  4. Confirm the PPW parameter endpoint exists
    Send an HTTP POST request to the device's web interface endpoint that handles the fromWizardHandle function, including the PPW parameter with test data
    Affected if The device accepts requests to the vulnerable endpoint and processes the PPW parameter

The device is affected if it is a Tenda A18 running firmware version 15.03.05.05 and the web management interface with the PPW parameter endpoint is accessible.
