CVE-2025-7770

Tigo Energy's CCA device is vulnerable to insecure session ID generation in their remote API. The session IDs are generated using a predictable method based on the current timestamp, allowing attackers to recreate valid session IDs. When combined with the ability to circumvent session ID requirements for certain commands, this enables unauthorized access to sensitive device functions on connected solar optimization systems.

El dispositivo Tigo Energy's CCA es vulnerable a la generación insegura de identificadores de sesión en su API remota. Estos identificadores se generan mediante un método predecible basado en la marca de tiempo actual, lo que permite a los atacantes recrear identificadores de sesión válidos. Esto, junto con la capacidad de eludir los requisitos de identificador de sesión para ciertos comandos, permite el acceso no autorizado a funciones sensibles del dispositivo en los sistemas de optimización solar conectados.
