Tenda W30E V2 Lacks Rate Limiting on Authentication

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) do not enforce rate limiting or account lockout mechanisms on authentication endpoints. This allows attackers to perform unrestricted brute-force attempts against administrative credentials.

Tenda W30E V2 Allows Password Changes Without Verifying Current Password

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) allow account passwords to be changed through the maintenance interface without requiring verification of the existing password. This enables unauthorized password changes when access to the affected endpoint is obtained.

Tenda W30E V2 Hardcoded Default Password for Built-in Account

Shenzhen 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.

Tenda W30E V2 HTTP Responses Expose Plaintext Credentials

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) disclose sensitive account credentials in cleartext within HTTP responses generated by the maintenance interface. Because the management interface is accessible over unencrypted HTTP by default, credentials may be exposed to network-based interception.

Tenda W30E V2 Incorrect Authorization Allows Administrator Password Change

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) contain an authorization flaw in the user management API that allows a low-privileged authenticated user to change the administrator account password. By sending a crafted request directly to the backend endpoint, an attacker can bypass role-based restrictions enforced by the web interface and obtain full administrative privileges.

Tenda W30E V2 Missing Cache Controls for Credential-bearing Pages

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) serve sensitive administrative content without appropriate cache-control directives. As a result, browsers may store credential-bearing responses locally, exposing them to subsequent unauthorized access.

Tenda W30E V2 Web UI Reveals Passwords in Cleartext
