Dell EMC Integrated System for Microsoft Azure Stack Hub, versions 1906 – 2011, contain an undocumented default iDRAC account. A remote unauthenticated attacker, with the knowledge of the default credentials, could potentially exploit this to log in to the system to gain root privileges.

Weakness

The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.

Affected Software

Extended Description

Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
