CVE-2023-48292
XWiki Admin Tools Application Run Shell Command allows CSRF RCE attacks
En resumen
XWiki Admin Tools permite que atacantes ejecuten comandos peligrosos en el servidor si engañan a un administrador para que haga clic en un enlace malicioso, como uno oculto en un comentario. Esto evita las verificaciones de seguridad normales y permite que los atacantes tomen control total del wiki.
Detalle técnico
Vulnerabilidad de falsificación de solicitud entre sitios (CSRF) en XWiki Admin Tools versiones 4.4 a 4.5.0 permite que atacantes no autenticados ejecuten comandos shell arbitrarios en el servidor mediante una URL manipulada, explotando la falta de validación de token de formulario. La salida del comando es vulnerable a inyección de sintaxis XWiki, permitiendo ejecución de código Groovy y compromiso completo del sistema.
Resumen generado y traducido por IA a partir de la descripción oficial.
The XWiki Admin Tools Application provides tools to help the administration of XWiki. Starting in version 4.4 and prior to version 4.5.1, a cross site request forgery vulnerability in the admin tool for executing shell commands on the server allows an attacker to execute arbitrary shell commands by tricking an admin into loading the URL with the shell command. A very simple possibility for an attack are comments. When the attacker can leave a comment on any page in the wiki it is sufficient to include an image with an URL like `/xwiki/bin/view/Admin/RunShellCommand?command=touch%20/tmp/attacked` in the comment. When an admin views the comment, the file `/tmp/attacked` will be created on the server. The output of the command is also vulnerable to XWiki syntax injection which offers a simple way to execute Groovy in the context of the XWiki installation and thus an even easier way to compromise the integrity and confidentiality of the whole XWiki installation. This has been patched by adding a form token check in version 4.5.1 of the admin tools. Some workarounds are available. The patch can be applied manually to the affected wiki pages. Alternatively, the document `Admin.RunShellCommand` can also be deleted if the possibility to run shell commands isn't needed.
