  • Source referenceurl.sap
Upstream source description

Applications based on SAP GUI for HTML in SAP NetWeaver Application Server ABAP do not sufficiently sanitize user-supplied content in certain functionality, allowing an authenticated attacker to send malicious content to another user. If the victim interacts with the affected content, malicious scripts could be executed in the victim's browser context. This vulnerability has a low impact on the confidentiality and integrity of the data and no impact on the availability of the application.
