CVE-2024-9491

Privilege escalation via installer DLL search path

Published Jan 24, 2025 · Updated Feb 12, 2025

Uncontrolled DLL search in Silicon Labs Configuration Wizard 2 4.50 and earlier allows local users to execute code with elevated privileges. The installer searches an attacker-controllable path for a DLL and loads the planted library without constraining the search to a trusted location. Execution requires a user to run the impacted installer, after which the planted DLL runs with the installer's privileges and can alter or interrupt the host.
