DescriptionNVD

Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.3.0.0, contains a use of hard-coded credentials vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability, leading to filesystem access for attacker.

AnalysisAI

Hard-coded credentials in Dell ECS 3.8.1.0-3.8.1.7 and ObjectScale <4.3.0.0 allow unauthenticated filesystem access. Despite CVSS 9.8 (network vector), the description explicitly states 'local access' is required, creating a critical discrepancy between scoring and actual attack surface. …
