CVE-2020-14231

Estado: ModificadaAlta (8.8)—

A vulnerability in the input parameter handling of HCL Client Application Access v9 could potentially be exploited by an authenticated attacker resulting in a stack buffer overflow. This could allow the attacker to crash the program 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).
