Detailed vulnerability description
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in com/dotmarketing/servlets/AjaxFileUploadServlet.class in dotCMS 4.1.1. A remote authenticated attacker can send a specially crafted HTTP request and remote authenticated administrators to upload .jsp files to arbitrary locations via directory traversal sequences in the fieldName parameter to servlets/ajax_file_upload. This results in arbitrary code execution by requesting the .jsp file at a /assets URI.
