CVE-2021-3848

Status: ModifiedMedium (5.5)—

An arbitrary file creation by privilege escalation vulnerability in Trend Micro Apex One, Apex One as a Service, Worry-Free Business Security 10.0 SP1, and Worry-Free Business Security Services could allow a local attacker to create an arbitrary file with higher privileges that could lead to a denial-of-service (DoS) on affected installations. 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

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
