    Title
    Unauthenticated Credential Disclosure via /goform/ate in Nexxt Nebula 300+
    Summary
    Missing authentication in the /goform/ate endpoint in Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 allows an adjacent unauthenticated attacker to retrieve sensitive device information, including the administrator password. The endpoint returns a raw response containing parameters such as Login_PW, which is Base64-encoded. An attacker can decode this value to obtain valid administrative credentials and authenticate to the device.
