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.

TAIWAN-CA(TWCA) JCICSecurityTool's Registry-related functions have insufficient filtering for special characters. An unauthenticated remote attacker can inject malicious script into a webpage to perform XSS (Stored Cross-Site Scripting) attack.
