CVE-2026-24431
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 · uneditedShenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) display stored user account passwords in plaintext within the administrative web interface. Any user with access to the affected management pages can directly view credentials.
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 confidenceThe Tenda W30E V2 router firmware versions up to V16.01.0.19(5037) stores user account credentials and displays them in plaintext within the administrative web interface. Any authenticated user with access to the affected management pages can directly view all stored passwords, representing a sensitive information disclosure vulnerability.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelCheck the router label or access the admin web interface to confirm the device is a Tenda W30EAffected if The device is not a Tenda W30E router, then this CVE does not apply
-
Determine the firmware versionAccess the router admin web interface, typically at 192.168.0.1, and navigate to System Status or Firmware Version page to read the installed firmware version. Alternatively, check the firmware file name if you have direct access to the firmware image.Affected if The firmware version is greater than 16.01.0.19(5037), the device is not vulnerable. Versions up to and including 16.01.0.19(5037) are affected.
-
Verify admin interface accessLog into the router administrative web interface with valid user credentialsAffected if Without valid authentication credentials, the password disclosure page cannot be accessed, though the vulnerability still exists in the firmware
-
Check for plaintext password displayNavigate to the user management or account settings page within the admin interface and observe whether stored passwords are displayed in plaintext rather than masked or shown as hashed valuesAffected if If stored passwords appear in plaintext on any admin page, the device is confirmed as vulnerable to CVE-2026-24431
A Tenda W30E router running firmware version 16.01.0.19(5037) or lower where the admin web interface displays user passwords in plaintext is affected by this CVE.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict access to the administrative web interface to trusted users only until a patched firmware version is available from Tenda that properly hashes stored passwords instead of displaying them in plaintext.
