Executive Summary

This vulnerability is a privilege escalation issue caused by DLL hijacking in Inno Setup version 6.2.1 and earlier. DLL hijacking occurs when an attacker places a malicious DLL file in a location where the application loads it instead of the legitimate DLL, allowing the attacker to execute code with elevated privileges.

Impact Analysis

The impact of this vulnerability is that an attacker could exploit the DLL hijacking flaw to escalate their privileges on the affected system. This means the attacker could gain higher-level access than intended, potentially allowing them to execute unauthorized actions or compromise system security.
