Description

A vulnerability exists in the Credential Manager component that may allow for unauthorized administrative access. An unauthenticated remote attacker could exploit this vulnerability on a device in its factory-default or post-ZTP state before any administrator has configured credentials by providing a predictable factory-default password. Successful exploitation could result in full administrative control of the affected device during the initial setup process.
