What the vulnerability does

01Description

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) implement an insecure Cross-Origin Resource Sharing (CORS) policy on authenticated administrative endpoints. The device sets Access-Control-Allow-Origin: * in combination with Access-Control-Allow-Credentials: true, allowing attacker-controlled origins to issue credentialed cross-origin requests.
