Delta Electronics InfraSuite Device Master Privilege Escalation

High

Synopsis

A privilege escalation vulnerability exists in Delta Electronics InfraSuite Device Master 00.00.02a. 

A default user 'User', which is in the 'Read Only User' group, can view the password of another default user 'Administrator', which is in the 'Administrator' group.

When the User account logs into the InfraSuite Device Master Device-Gateway web UI and navigates to the user management page (i.e., by clicking Configure -> User -> User -> Users), the Administrator account is not visible in the UI. However, the information about that account (including the base64-encoded password) is present in the network traffic returned to the browser.

The user can then use this information to log into the Administrator account.

Solution

At the time of this writing, the vendor has not provided a solution for this issue.
