DescriptionCVE.org

Dell ECS, versions 3.8.1.0 through 3.8.1.7, and Dell ObjectScale versions prior to 4.2.0.0, contains an Use of Default Credentials vulnerability in the OS. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Elevation of privileges.

AnalysisAI

Privilege escalation in Dell ECS 3.8.1.0-3.8.1.7 and ObjectScale prior to 4.2.0.0 stems from hardcoded default credentials in the operating system that a remote authenticated attacker can leverage to gain elevated privileges. An attacker with low-level access can exploit this vulnerability to achieve full system compromise including confidentiality, integrity, and availability impacts. No patch is currently available for affected versions.
