Descriptions

TikiWiki 21.2 allows templates to be edited without CSRF protection. This could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to follow a maliciously crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. These action include allowing attackers to submit their own code through an authenticated user resulting in local file Inclusion. If an authenticated user who is able to edit TikiWiki templates visits an malicious website, template code can be edited.

TikiWiki versión 21.2, permite plantillas para ser editadas sin protección de tipo CSRF. Esto podría permitir a un atacante remoto no autenticado conducir un ataque de tipo cross-site request forgery (CSRF) y llevar a cabo unas protecciones CSRF insuficientes para la interfaz de administración basada en web del sistema afectado. Un atacante podría explotar esta vulnerabilidad al persuadir a un usuario de la interfaz a seguir un vínculo diseñado maliciosamente. Una explotación con éxito podría permitir a un atacante llevar a cabo acciones arbitrarias en un sistema afectado con los privilegios del usuario. Estas acciones incluyen permitir a atacantes enviar su propio código por medio de un usuario autenticado, resultando una inclusión de archivo local. Si un usuario autenticado que es capaz de editar las plantillas TikiWiki visita un sitio web malicioso, el código de la plantilla puede ser editado
