Sistemas Afectados

1. Descripción

   Debian liberó una actualización para phpGroupWare. Esta repara varias vulnerabilidades que pueden explotarse por usuarios maliciosos para realizar ataques de inserción de scripts, o por personas malicosas para burlar ciertas restricciones de seguridad o comprometer un sistema vulnerable.

   1. Stefan Esser descubrió otra vulnerabilidad en las bibliotecas XML-RPC, que permitía la inyección de código PHP arbitrario en las sentencias eval(). El componente XMLRPC se ha desactivado.(CAN-2005-2498)

   2. Alexander Heidenreich descubrió un problema de guiones a través del sitio en la vista del árbol del sofware de tablón de anuncios FUD Forum, que también estaba presente en phpgroupware.(CAN-2005-2600)

   3. También se ha corregido una vulnerabilidad global de guiones a través del sitio, que también protege frente a guiones perniciosos incrustados en CSS y xmlns en varias partes de la aplicación y de los módulos.(CAN-2005-2761)

2. Impacto

3. Solución
