Silverpeas 6.4.2 contains a stored cross-site scripting (XSS) vulnerability in the event management module. An authenticated user can upload a malicious SVG file as an event attachment, which, when viewed by an administrator, executes embedded JavaScript in the admin's session. This allows attackers to escalate privileges by creating a new administrator account. The vulnerability arises from insufficient sanitization of SVG files and weak CSRF protections.

Summary
  • (es) Silverpeas 6.4.2 contiene una vulnerabilidad de cross-site scripting (XSS) almacenado en el módulo de gestión de eventos. Un usuario autenticado puede subir un archivo SVG malicioso como adjunto a un evento, el cual, al ser visto por un administrador, ejecuta JavaScript incrustado en su sesión. Esto permite a los atacantes escalar privilegios creando una nueva cuenta de administrador. La vulnerabilidad se debe a una limpieza insuficiente de los archivos SVG y a una protección CSRF deficiente.
