Executive brief
SAP NetWeaver Application Server ABAP contains a reflected cross-site scripting (XSS) vulnerability that allows authenticated attackers to inject malicious scripts into links. If a user clicks a crafted link, the attacker's code executes in their browser, potentially enabling account compromise, data theft, or fraud. The vulnerability requires the victim to be authenticated and click a malicious link, limiting its reach but posing a significant risk to organizations running SAP ERP systems.
Technical details
This is a reflected cross-site scripting (XSS) vulnerability in SAP NetWeaver Application Server ABAP. An authenticated attacker can craft a malicious link containing JavaScript or other executable code; when an authenticated victim visits the link, the input is processed and reflected in the DOM without proper sanitization, causing the injected script to execute in the victim's browser context. The attack requires both the attacker and victim to be authenticated users. Successful exploitation could result in session hijacking, credential theft, or other client-side attacks affecting confidentiality and integrity. A patch is available via SAP Security Note 3721424 on the SAP Security Patch Day (August 11, 2026).
