CVE-2024-34474

SYSTEM privilege escalation via writable DLL search paths

Published May 5, 2024 · Updated Aug 21, 2024

Local privilege escalation in Clario Desktop through 2024-04-11 allows local users to execute arbitrary code as SYSTEM. ClarioService.exe searches weakly permissioned ProgramData directories for missing DLLs and loads a planted library with SYSTEM privileges. A low-privileged Windows account must place a matching DLL and start an antivirus scan; successful exploitation grants complete SYSTEM control.
