Estado: ModificadaAlta (7.8)—

In Cylance CylancePROTECT before 1470, an unprivileged local user can obtain SYSTEM privileges because users have Modify access to the %PROGRAMFILES%\Cylance\Desktop\log folder, the CyUpdate process grants users Modify access to new files created in this folder, and a new file can be a symlink chain to a pathname of an arbitrary DLL that CyUpdate uses.
