CVE-2026-24429
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) ship with a predefined default password for a built-in authentication account that is not required to be changed during initial configuration. An attacker can leverage these default credentials to gain authenticated access to the management interface.
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)) ships with a built-in administrative account that has a static, predefined default password. This password is not forced to be changed during the initial setup process, leaving the account accessible using known default credentials. An unauthenticated remote attacker can leverage these credentials to gain full authenticated access to the router's web management interface.

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 device model and firmware versionAccess the router's web management interface and check the System Status or Firmware Version page. Alternatively, check via CLI or look for a sticker on the device showing model W30E and firmware version.Affected if The device is a Tenda W30E V2 and the firmware version is <= 16.01.0.19(5037)
-
Locate the default administrative accountAccess the router's User Management or Admin Account settings page within the web management interface. Look for a built-in administrator account that ships with the firmware (typically named 'admin' or similar default name).Affected if A built-in administrative account exists that was not created by the user but came pre-configured with the firmware
-
Verify if default password is still in useAttempt to log in using the known default credentials for the built-in account, or inspect whether the password has been changed from the factory default. Check if the router forces password change on first login.Affected if The built-in administrative account is still using its factory default password or the router never prompted for a password change during initial setup
The environment is affected if it is a Tenda W30E V2 router running firmware version 16.01.0.19(5037) or earlier, and the built-in administrative account retains its default static password without having been changed by the administrator.

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.
dbcve · scopedImmediately change the default credentials for any built-in accounts on affected Tenda W30E V2 devices. If available, apply vendor firmware updates. Until patched, restrict management interface access to trusted networks or disable remote management entirely.
- Access the Tenda W30E management interface via web browser at the device's IP address
- Log in using the current default credentials
- Navigate to the administrative settings or user management section
- Locate the built-in authentication account settings
- Change the default password to a strong, unique password that meets complexity requirements
- Save the configuration changes
- Verify the new password works by logging out and logging back in
- Check the vendor website (www.tendacn.com) periodically for firmware updates that address this vulnerability
