Vulnerability from fkie_nvd - Published: 2023-12-15 09:15 - Updated: 2026-06-17 06:34

Severity

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

Summary

TAIWAN-CA(TWCA) JCICSecurityTool fails to check the source website and access locations when executing multiple Registry-related functions. In the scenario where a user is using the JCICSecurityTool and has completed identity verification, if the user browses a malicious webpage created by an attacker, the attacker can exploit this vulnerability to read or modify any registry file under HKEY_CURRENT_USER, thereby achieving remote code execution.
