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.
