  3. CVE-2026-31846
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.

Summary
  • (es) Una vulnerabilidad de divulgación de credenciales no autenticada en el endpoint /goform/ate del firmware Nexxt Solutions Nebula 300+ hasta Nebula300+_v12.01.01.37 permite a un atacante adyacente obtener la contraseña de administrador en formato codificado en Base64 a través de una solicitud HTTP manipulada. La credencial recuperada puede ser utilizada para autenticarse en el dispositivo y facilita un compromiso adicional cuando se combina con otras debilidades presentes en el firmware.
