Alert meAnalysisAIv1 – Mar 12, 2026
Unauthenticated password modification in Tenda W30E V2 firmware through the maintenance interface allows authenticated users to reset account credentials without password verification, potentially enabling privilege escalation or account takeover on affected devices. The vulnerability affects firmware versions up to V16.01.0.19(5037) and currently lacks an available patch.
Earlier versions of this analysis (1)
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. [CVSS 8.8 HIGH]

DescriptionCVE.org
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.
Executive ViewAI
Tenda W30E V2 routers are vulnerable to unauthorized password changes, allowing attackers with physical or network access to take control of affected devices without authentication. Organizations using this equipment face potential network compromise, unauthorized access to connected systems, and loss of administrative control until remediation is completed.
Restrict network access to the maintenance interface via firewall rules and network segmentation; disable remote management/WAN access to administrative functions; implement physical access controls to prevent unauthorized local connections; monitor administrative logs for suspicious password change attempts; consider replacing affected devices with alternative vendors that provide timely security patches.
