OS Command Injection in Chamilo LMS 1.11.36_CVE-2026-32892

{
    "lastseen": "",
    "description": "Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, Chamilo LMS contains an OS Command Injection vulnerability in the file move function. The move() function in fileManage.lib.php passes user-controlled path values directly into exec() shell commands without using escapeshellarg(). When a user moves a document via document.php, the move_to POST parameter \u2014 which only passes through Security::remove_XSS() (an HTML-only filter) \u2014 is concatenated directly into shell commands such as exec(\"mv $source $target\"). By default, Chamilo allows all authenticated users to create courses (allow_users_to_create_courses = true). Any user who is a teacher in a course (including self-created courses) can move documents, making this vulnerability exploitable by any authenticated user. The attacker must first place a directory with shell metacharacters in its name on the filesystem (achievable via Course Backup Import), then move a document into that directory to trigger arbitrary command execution as the web server user (www-data). This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.",
