CVE-2021-45442

Estado: ModificadaAlta (7.1)—

A link following denial-of-service vulnerability in Trend Micro Worry-Free Business Security (on prem only) could allow a local attacker to overwrite arbitrary files in the context of SYSTEM. This is similar to, but not the same as CVE-2021-44024. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

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).
