Descriptions

Cross-site request forgery (CSRF) vulnerability in system/workplace/admin/accounts/user_role.jsp in OpenCMS 10.5.3 allows remote attackers to hijack the authentication of administrative users for requests that perform privilege escalation. Note: It is argued that OpenCMS allows only registered users to upload different kind of content artifacts (SVG, .doc, .docx). The uploaded content is stored in the CMS content repository "as is". In case of scripts inside an SVG, this may or may not be "malicious", there is no way of knowing if the uploaded SVG contains the script for a reason. To exploit the "issue", a user must have an account in the CMS as a content manager

** EN DISPUTA ** Vulnerabilidad de Cross-Site Request Forgery (CSRF) en system/workplace/admin/accounts/user_role.jspen OpenCMS versión 10.5.3 permite a los atacantes remotos secuestrar la autenticación de los usuarios administrativos para peticiones que realizan una escalada de privilegios. Nota: Se argumenta que OpenCMS sólo permite a los usuarios registrados subir diferentes tipos de artefactos de contenido (SVG, .doc, .docx). El contenido cargado se almacena en el repositorio de contenido del CMS "tal cual". En el caso de los scripts dentro de un SVG, esto puede o no ser "malicioso", no hay forma de saber si el SVG subido contiene el script por alguna razón. Para explotar el "problema", un usuario debe tener una cuenta en el CMS como administrador de contenido.

OpenCMS version 10.5.3 suffers from a cross site request forgery vulnerability.
