XWiki Platform Web Templates vulnerable to Unauthorized User Registration Through the Distribution Wizard

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 授权问题漏洞

XWiki Platform是法国XWiki公司的一套用于创建Web协作应用程序的Wiki平台。 XWiki Platform Web Templates 13.10.5之前版本和14.3RC1之前版本存在安全漏洞，该漏洞源于通过将分发向导的模板传递给xpart模板，即使禁用了用户注册，也可以创建用户帐户，这绕过了任何电子邮件验证，这可以在私有wiki上被利用，从而可能使攻击者访问wiki，根据用户配置的默认权限，这也可能使攻击者拥有对其他只读公共wiki的写入权限，也可以在配置了LDAP等外部身份验证系
