## Technical details

An incorrect authorization vulnerability (CWE-863) exists in the REST API endpoint for devices within Subnet Solutions PowerSYSTEM Center. The flaw allows an authenticated attacker with low-level privileges to bypass operational permission checks and retrieve sensitive device information. The attack vector is restricted to the adjacent network (AV:A), meaning the attacker must have access to the local or management network where the system resides. Successful exploitation results in a loss of confidentiality regarding device data. The issue is addressed in PowerSYSTEM Center 2020 Update 29, 2024 Update 2, and 2026 GA Hotfix.
