Descriptions

XWiki Platform Web Templates are templates for XWiki Platform, a generic wiki platform. By passing a template of the distribution wizard to the xpart template, user accounts can be created even when user registration is disabled. This also circumvents any email verification. Before versions 14.2 and 13.10.4, this can also be exploited on a private wiki, thus potentially giving the attacker access to the wiki. Depending on the configured default rights of users, this could also give attackers write access to an otherwise read-only public wiki. Users can also be created when an external authentication system like LDAP is configured, but authentication fails unless the authentication system supports a bypass/local accounts are enabled in addition to the external authentication system. This issue has been patched in XWiki 13.10.5 and 14.3RC1. As a workaround, one may replace `xpart.vm`, the entry point for this attack, by a patched version from the patch without updating XWiki.

XWiki Platform Web Templates son plantillas para la plataforma XWiki, una plataforma wiki genérica. Al pasar una plantilla del asistente de distribución a la plantilla xpart, pueden crearse cuentas de usuario incluso cuando el registro de usuario está deshabilitado. Esto también omite cualquier verificación de correo electrónico. En versiones anteriores a 14.2 y 13.10.4, esto también puede explotarse en una wiki privada, potencialmente dándole al atacante acceso a la wiki. Dependiendo de los derechos predeterminados configurados de usuarios, esto también podría dar a atacantes acceso de escritura a un wiki público de solo lectura. También pueden crearse usuarios cuando es configurado un sistema de autenticación externo como LDAP, pero la autenticación falla a menos que el sistema de autenticación admita una omisión/cuentas locales habilitadas además del sistema de autenticación externo. Este problema fue parcheado en XWiki versiones 13.10.5 y 14.3RC1. Como mitigación, puede sustituirse "xpart.vm", el punto de entrada de este ataque, por una versión parcheada del parche sin actualizar XWiki
