CVE-2021-28649

Estado: ModificadaAlta (7.3)—

An incorrect permission vulnerability in the product installer for Trend Micro HouseCall for Home Networks version 5.3.1179 and below could allow an attacker to escalate privileges by placing arbitrary code on a specified folder and have that code be executed by an Administrator who is running a scan. Please note that an attacker must first obtain the ability to execute low-privileged code on the target system 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).
