Privilege escalation via DLL search-path hijacking
Published Apr 12, 2022 · Updated Aug 3, 2024
DLL hijacking in Siemens SIMATIC Energy Manager Basic and PRO before V7.3 Update 1 allows local users to execute elevated code. The affected application searches a DLL path containing a directory where a local user can place a malicious library, then loads that library. Exploitation requires low-privileged local access and user interaction, after which attacker-controlled code runs with elevated privileges.
