CVE-2024-13454

Estado: AnalizadaMedia (5.3)—

Weak encryption algorithm in Easy-RSA version 3.0.5 through 3.1.7 allows a local attacker to more easily bruteforce the private CA key when created using OpenSSL 3

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).
