Official description
Due to misconfigured application endpoints, SAP SuccessFactors attachment APIs allow attackers with user privileges to perform activities with admin privileges over the network. These APIs were consumed in the SF Mobile application for Time Off, Time Sheet, EC Workflow, and Benefits. On successful exploitation, the attacker can read/write attachments. Thus, compromising the confidentiality and integrity of the application

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.
