CVE-2021-32497

Code execution via unchecked SDD emulator executable

Published Dec 17, 2021 · Updated Aug 3, 2024

Code execution in SICK AG SOPAS Engineering Tool before 4.8.0 allows local attackers to run an executable through a crafted SDD file. An SDD can embed an arbitrary executable and register it as an emulator, which SOPAS ET launches without validating the bundled program. Execution requires a user to install the attacker-supplied SDD and start its emulator, after which the program runs with that user's privileges.
