Title: Chamilo Unrestricted Upload of File with Dangerous Type Vulnerability

Overview:

Chamilo LMS 1.11.8 and 2.x allows remote code execution through an lp_upload.php unauthenticated file upload feature. It extracts a ZIP archive before checking its content and once it has been extracted does not check files in a recursive way. This means that by putting a .php file in a folder and then this folder in a ZIP archive the server will accept this file without any checks. Because one can access this file from the website it is remote code execution. This is related to a scorm imsmanifest.xml file the import_package function and extraction in courseSysDir.newDir.
