CVE-2023-51711

Local code execution via DLL search-path hijacking

Published Jan 24, 2024 · Updated May 30, 2025

DLL hijacking in Regify Regipay Client for Windows 4.5.1.0 allows local users to execute arbitrary code when the client starts. The client resolves an unspecified DLL through an uncontrolled search-path element, loading attacker-supplied code instead of the intended library. Exploitation requires local placement of a crafted DLL and execution of the client; the code runs in the client's security context.
