CVE-2022-48223

Privilege escalation via repair-time DLL hijacking

Published Apr 4, 2023 · Updated Feb 18, 2025

DLL search-order hijacking in Acuant AcuFill SDK before 10.22.02.03 allows local users to execute code during SDK repair. The installer invokes certutil.exe to repair certificates from an execution directory with insecure permissions, creating a race in which an attacker-controlled DLL can be loaded. A local low-privileged user must win the repair-time race and induce the installer action; successful code runs with the installer's elevated privileges.
