Official description

A vulnerability has been identified in Micro Focus ZENworks 2020 Update 3a and prior versions. This vulnerability allows administrators with rights to perform actions (e.g., install a bundle) on a set of managed devices, to be able to exercise these rights on managed devices in the ZENworks zone but which are outside the scope of the administrator. This vulnerability does not result in the administrators gaining additional rights on the managed devices, either in the scope or outside the scope of the administrator.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
