CVE-2026-32892— Chamilo LMS 操作系统命令注入漏洞

OS Command Injection in Chamilo LMS 1.11.36

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 — which only passes through Security::remove_XSS() (an HTML-only filter) — 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.

Chamilo LMS 操作系统命令注入漏洞

Chamilo LMS是Chamilo开源的一套开源的在线学习和协作系统。该系统支持创建教学内容、远程培训和在线答题等。 Chamilo LMS 1.11.38之前版本和2.0.0-RC.3之前版本存在操作系统命令注入漏洞，该漏洞源于fileManage.lib.php中move函数将用户控制的路径值直接传递给exec命令，可能导致OS命令注入攻击。
