Technical details
An incorrect authorization vulnerability (CWE-863) exists in the device project groups feature of Subnet Solutions PowerSYSTEM Center. The flaw allows an authenticated attacker with limited permissions to bypass intended access controls and perform unauthorized deletions of project groups. The attack vector is restricted to the adjacent network (AV:A), and exploitation requires valid low-privilege credentials. Successful exploitation impacts system integrity and availability by allowing the removal of organizational data. Subnet Solutions has released updates (PSC 2024 Update 2 and PSC 2026 GA Hotfix) to address this issue.
