Vulnerability from fkie_nvd - Published: 2020-09-29 00:15 - Updated: 2026-06-17 03:05

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

A vulnerability in Trend Micro OfficeScan XG SP1 on Microsoft Windows may allow an attacker to create a hard link to any file on the system, which then could be manipulated to gain a privilege escalation and code execution. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. This CVE is similar, but not identical to CVE-2020-24556.
