Descriptions

A cross-site scripting (XSS) vulnerability was discovered in the legacy IBM and Lenovo System x IMM2 (Integrated Management Module 2), prior to version 5.60, embedded Baseboard Management Controller (BMC) web interface during an internal security review. This vulnerability could allow JavaScript code to be executed in the user's web browser if the user is convinced to visit a crafted URL, possibly through phishing. Successful exploitation requires specific knowledge about the user’s network to be included in the crafted URL. Impact is limited to the normal access restrictions and permissions of the user clicking the crafted URL, and subject to the user being able to connect to and already being authenticated to IMM2 or other systems. The JavaScript code is not executed on IMM2 itself.

Se detectó una vulnerabilidad de tipo cross-site scripting (XSS) en la interfaz web legacy de IBM y Lenovo System x IMM2 (Módulo Integrated Management 2) versiones anteriores a 5.60, una interfaz web Baseboard Management Controller (BMC) integrada durante una revisión de seguridad interna. Esta vulnerabilidad podría permitir al código JavaScript ser ejecutado en el navegador web del usuario, si el usuario está convencido de visitar una URL diseñada, posiblemente por medio de phishing. Una explotación con éxito requiere que sean incluidos conocimientos específicos sobre la red del usuario en la URL diseñada. El impacto es limitado a las restricciones y permisos de acceso normales del usuario que hace clic en la URL diseñada, y está sujeto a que el usuario pueda conectarse y ya esté autenticado en IMM2 u otros sistemas. El código JavaScript no es ejecutado en el propio IMM2
