Official description
Due to a Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Application Server ABAP, an authenticated attacker could generate a malicious link and make it publicly accessible. If an authenticated victim accesses this link, the injected input is processed and reflected within the DOM on the client side during page rendering, resulting in the execution of malicious content in the victim's browser context. Successful exploitation could result in a high impact to the confidentiality and a low impact to the integrity of the system, while availability remains unaffected.
