La vulnerabilidad de administración de privilegios inadecuada en Zyxel GS1900-24EP switch firmware versión V2.70 (ABTO.5) podría permitir que un usuario local autenticado con acceso de solo lectura modifique la configuración del sistema en un dispositivo vulnerable. • https://www.zyxel.com/global/en/support/security-advisories/zyxel-security-advisory-for-improper-privilege-management-vulnerability-in-gs1900-series-switches • CWE-269: Improper Privilege Management •
CVE-2022-45853
https://notcve.org/view.php?id=CVE-2022-45853
The privilege escalation vulnerability in the Zyxel GS1900-8 firmware version V2.70(AAHH.3) and the GS1900-8HP firmware version V2.70(AAHI.3) could allow an authenticated, local attacker with administrator privileges to execute some system commands as 'root' on a vulnerable device via SSH. • https://www.zyxel.com/global/en/support/security-advisories/zyxel-security-advisory-for-privilege-escalation-vulnerability-in-gs1900-series-switches • CWE-269: Improper Privilege Management •
CVE-2022-34746
https://notcve.org/view.php?id=CVE-2022-34746
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 •
