AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
