Status: ModifiedHigh (7.8)—

Trend Micro Antivirus for Mac 2020 (Consumer) is vulnerable to a symbolic link privilege escalation attack where an attacker could exploit a critical file on the system to escalate their privileges. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

CVSS
