Summary
Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Application Server ABAP. An authenticated attacker can create a malicious link and make it publicly accessible. When an authenticated victim clicks the link, the injected input is processed and reflected in the DOM on the client side, leading to execution of malicious content in the victim's browser.
Risk Assessment
Successful exploitation could have a high impact on confidentiality and a low impact on integrity, while availability remains unaffected. This could lead to exposure or manipulation of sensitive data.
Recommendation
Apply SAP patches immediately and review input sanitization in SAP NetWeaver-based applications.
