CVE-2024-13946Public exploit

Code execution via unsafe CylonLicence DLL search

Published May 22, 2025 · Updated May 22, 2025

DLL hijacking in ABB ASPECT products through 3.08.03 allows local users to execute code through the configuration toolset. ASPECT-Studio calls System.loadLibrary for CylonLicence without a full path, causing Java to search writable locations for CylonLicence.dll. A local user must plant the library and induce a commissioning workflow; the code then runs with the toolset user's privileges.
