Summary
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.

Los identificadores de sesi\u00f3n son predecibles, con solo 32 768 valores posibles por usuario, lo que permite a los atacantes generar previamente identificadores de sesi\u00f3n v\u00e1lidos, 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 funci\u00f3n rand() (insegura), sino tambi\u00e9n a la falta de inicializaci\u00f3n a trav\u00e9s de srand(). Como resultado, solo los identificadores PID se utilizan de manera efectiva como semilla."
