CVE-2025-55069

Estado: AplazadaAlta (8.7)—

A predictable seed in pseudo-random number generator vulnerability has been discovered in firmware version 3.60 of the Click Plus PLC. The vulnerability relies on the fact that the software implements a predictable seed for its pseudo-random number generator, which compromises the security of the generated private keys.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

UI:R indica interacción del usuario (firmware 3.60). Acceso a red sin privilegios requiere que el usuario instale/interactúe con código malicioso. CWE-337 (predictable seed) compromete generación de claves privadas: impacto primario acceso a credenciales (T1212), secundario manipulación de identidad

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
