Details

Due to improper input handling under certain conditions, SAP NetWeaver Application Server ABAP allows an attacker to inject custom Cascading Style Sheets (CSS) data into a web page served by the application. When a user accesses or clicks the affected page, the injected CSS is executed. As a result, the issue has a low impact on confidentiality, while integrity and availability are not impacted.

Severity
