CVE-2024-47945

The devices are vulnerable to session hijacking due to insufficient entropy in its session ID generation algorithm. The session IDs are predictable, with only 32,768 possible values per user, which allows attackers to pre-generate valid session IDs, leading to unauthorized access to user sessions. This is not only due to the use of an (insecure) rand() function call but also because of missing initialization via srand(). As a result only the PIDs are effectively used as seed.

Summary
  • (es) Los dispositivos son vulnerables al secuestro de sesiones debido a la entropía insuficiente en su algoritmo de generación de identificadores de sesión. Los identificadores de sesión son predecibles, con solo 32 768 valores posibles por usuario, lo que permite a los atacantes generar previamente identificadores de sesión válidos, lo que conduce a un acceso no autorizado a las sesiones de usuario. Esto no solo se debe al uso de una llamada a la función rand() (insegura), sino también a la falta de inicialización a través de srand(). Como resultado, solo los identificadores PID se utilizan de manera efectiva como semilla.
