AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in SAP NetWeaver Application Server ABAP and ABAP Platform. It allows an authenticated user with low privileges to perform background Remote Function Calls (RFCs) without having the required S_RFC authorization in certain situations.
Essentially, this means that users who should not have permission to execute certain remote functions can bypass authorization checks and perform these actions.
How can this vulnerability impact me? :
The vulnerability can have a high impact on the integrity and availability of the affected SAP system.
Since unauthorized background Remote Function Calls can be executed, it may lead to unauthorized changes or disruptions in the system's operations.
However, there is no impact on the confidentiality of the application, meaning sensitive data exposure is not a concern in this case.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
