      "value": "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."

      "value": "Debido a una vulnerabilidad de cross-site scripting (XSS) en SAP NetWeaver Servidor de aplicaciones ABAP, un atacante autenticado podría generar un enlace malicioso y hacerlo accesible públicamente. Si una víctima autenticada accede a este enlace, la entrada inyectada es procesada y reflejada dentro del DOM en el lado del cliente durante la renderización de la página, resultando en la ejecución de contenido malicioso en el contexto del navegador de la víctima. La explotación exitosa podría resultar en un alto impacto a la confidencialidad y un bajo impacto a la integridad del sistema, mientras que la disponibilidad permanece inafectada."
