Administrative code execution via insecure DLL search
Published Apr 23, 2026 · Updated Apr 23, 2026
Uncontrolled DLL search path handling in IP Setting Software before 5.20 allows attackers to execute code as administrator. The software searches an attacker-influenceable path for a DLL and loads a matching library without restricting resolution to a trusted directory. Exploitation requires local low-privilege access, placement of a crafted DLL, and a privileged launch of the application; the payload then runs with administrative privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
