## Technical details

This vulnerability is an Improper Privilege Management issue affecting Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.4.0.0. The flaw allows a high-privileged attacker with local access to exploit improper privilege controls and escalate to higher privilege levels. The attack requires local system access and elevated privileges as a precondition. Successful exploitation results in privilege escalation, enabling the attacker to achieve high-impact compromise of confidentiality, integrity, and availability. A patch is available in version 4.4.0.0 or later for ObjectScale, and version 4.4.0.0 or later for ECS.
