An insufficient entropy vulnerability caused by the improper use of randomness sources with low entropy for RSA key pair generation was found in Zyxel GS1900 series firmware versions prior to V2.70. This vulnerability could allow an unauthenticated attacker to retrieve a private key by factoring the RSA modulus N in the certificate of the web administration interface. Se ha encontrado una vulnerabilidad de entropía insuficiente causada por el uso inapropiado de fuentes de aleatoriedad con baja entropía para la generación de pares de claves RSA en las versiones de firmware de la serie Zyxel GS1900 versiones anteriores a V2.70. Esta vulnerabilidad podría permitir a un atacante no autenticado recuperar una clave privada mediante la factorización del módulo N de RSA en el certificado de la interfaz de administración web • https://www.zyxel.com/global/en/support/security-advisories/zyxel-security-advisory-for-insufficient-entropy-vulnerability-of-gs1900-series-switches • CWE-331: Insufficient Entropy •
