CVE-2025-42886

Due to a Reflected Cross-Site Scripting (XSS) vulnerability in SAP Business Connector, an unauthenticated attacker could generate a malicious link and make it publicly accessible. If an authenticated victim accesses this link, the injected input is processed during web page generation, resulting in the execution of malicious content in the victim's browser context. This could allow the attacker to access or modify information within the victim�s browser scope, impacting confidentiality and integrity, while availability remains unaffected

Summary		(es) Debido a una vulnerabilidad de cross-site scripting (XSS) reflejado en SAP Business Connector, un atacante no autenticado podría generar un enlace malicioso y hacerlo accesible públicamente. Si una víctima autenticada accede a este enlace, la entrada inyectada se procesa durante la generación de la página web, lo que resulta en la ejecución de contenido malicioso en el contexto del navegador de la víctima. Esto podría permitir al atacante acceder o modificar información dentro del alcance del navegador de la víctima, lo que afecta la confidencialidad y la integridad, mientras que la disponibilidad no se ve afectada.
