CVE-2020-7497

Startup code execution via path traversal

Published Jun 16, 2020 · Updated Aug 4, 2024

Path traversal in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and earlier allows local users to execute code when Windows starts. Schneider Electric has not disclosed the path-handling locus or the file operation that accepts the traversal path. Exploitation requires high local privileges and user interaction; successful abuse causes attacker-controlled code to run at the next computer startup.
