CVE-2017-7463

JBoss BRMS 6 y BPM Suite 6 en versiones anteriores a la 6.4.3 son vulnerables a un Cross-Site Scripting (XSS) reflejado a través de la carga de artefactos. Un archivo XML mal formado, si se carga, provoca que aparezca un mensaje de error que incluye parte del código XML incorrecto verbatim sin filtrar los scripts. Su explotación exitosa permitiría la ejecución del código del script dentro del contexto del usuario afectado.

JBoss BRMS 6 and BPM Suite 6 are vulnerable to a reflected XSS via artifact upload. A malformed XML file, if uploaded, causes an error message to appear that includes part of the bad XML code verbatim without filtering out scripts. Successful exploitation would allow execution of script code within the context of the affected user.

Red Hat JBoss BRMS is a business rules management system for the management, storage, creation, modification, and deployment of JBoss Rules. This release of Red Hat JBoss BRMS 6.4.3 serves as a replacement for Red Hat JBoss BRMS 6.4.2, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix: JBoss BRMS 6 and BPM Suite 6 are vulnerable to a stored XSS via several lists in Business Central. The flaw is due to lack of sanitation of user input when creating new lists. Remote, authenticated attackers that have privileges to create lists can store scripts in them, which are not properly sanitized before showing to other users, including admins.
