CVE-2020-14224

Estado: ModificadaCrítica (9.8)—

A vulnerability in the MIME message handling of the HCL Notes v9 client could potentially be exploited by an unauthenticated attacker resulting in a stack buffer overflow. This could allow a remote attacker to crash the Notes application or inject code into the system which would execute with the privileges of the currently logged-in user.

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).
