Limited-admin privilege escalation via TOCTOU race
Published Jun 12, 2024 · Updated Aug 1, 2024
A TOCTOU race in Schneider Electric SpaceLogic AS-P and AS-B 5.0.3 and earlier allows local users to escalate privileges. Schneider Electric has not identified the raced resource or disclosed which check and later use can observe different state. Exploitation requires a limited administrator account and high-complexity local access, and successful abuse permits unauthorized configuration changes.
