CVE-2022-38493

Estado: ModificadaAlta (7.5)—

Rhonabwy 0.9.99 through 1.1.x before 1.1.7 doesn't check the RSA private key length before RSA-OAEP decryption. This allows attackers to cause a Denial of Service via a crafted JWE (JSON Web Encryption) token.

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).
