| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the gradebook result view page allows any authenticated teacher to delete any student's grade result across the entire platform by manipulating the delete_mark or resultdelete GET parameters. No ownership or course-scope verification is performed. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the gradebook evaluation edit page allows any authenticated teacher to view and modify the settings (name, max score, weight) of evaluations belonging to any other course by manipulating the editeval GET parameter. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an unrestricted file upload vulnerability in the exercise sound upload function allows an authenticated teacher to upload a PHP webshell by spoofing the Content-Type header to audio/mpeg. The uploaded file retains its original .php extension and is placed in a web-accessible directory, enabling Remote Code Execution as the web server user (www-data). This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an Open Redirect vulnerability in the session course edit page allows an attacker to redirect an authenticated administrator to an arbitrary external URL after saving coach assignment changes. The redirect also leaks the id_session parameter to the attacker's server. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
| CR/LF bytes were not rejected by HTTP client proxy tunnel headers or host. |
| 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 is a learning management system. Prior to 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the REST API stats endpoint allows any authenticated user (including low-privilege students with ROLE_USER) to read any other user's learning progress, certificates, and gradebook scores for any course, without enrollment or supervisory relationship. This vulnerability is fixed in 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to .0.0-RC.3, the PlatformConfigurationController::decodeSettingArray() method uses PHP's eval() to parse platform settings from the database. An attacker with admin access (obtainable via Advisory 1) can inject arbitrary PHP code into the settings, which is then executed when any user (including unauthenticated) requests /platform-config/list. This vulnerability is fixed in 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 1.11.38, a chained attack can enable otherwise-blocked PHP code from the main/install/ directory and allow an unauthenticated attacker to modify existing files or create new files where allowed by system permissions. This only affects portals with the main/install/ directory still present and read-accessible. This vulnerability is fixed in 1.11.38. |
| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, Chamilo LMS contains an Insecure Direct Object Reference (IDOR) vulnerability in the Learning Path progress saving endpoint. The file lp_ajax_save_item.php accepts a uid (user ID) parameter directly from $_REQUEST and uses it to load and modify another user's Learning Path progress — including score, status, completion, and time — without verifying that the requesting user matches the target user ID. Any authenticated user enrolled in a course can overwrite another user's Learning Path progress by simply changing the uid parameter in the request. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
| When calling base64.b64decode() or related functions the decoding process would stop after encountering the first padded quad regardless of whether there was more information to be processed. This can lead to data being accepted which may be processed differently by other implementations. Use "validate=True" to enable stricter processing of base64 data. |
| Chamilo LMS is a learning management system. Prior to 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the /social-network/personal-data/{userId} endpoint allows any authenticated user to access full personal data and API tokens of arbitrary users by modifying the userId parameter. This results in mass disclosure of sensitive user information and credentials, enabling a full platform data breach. This vulnerability is fixed in 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 1.11.38, any authenticated user (including students) can write arbitrary content to files on the server via the BigUpload endpoint. The key parameter controls the filename and the raw POST body becomes the file content. While .php extensions are filtered to .phps, the .pht extension passes through unmodified. On Apache configurations where .pht is handled as PHP, this leads to Remote Code Execution. This vulnerability is fixed in 1.11.38. |
| Chamilo LMS is a learning management system. Prior to 1.11.38, Twig template files (.tpl) under /main/template/default/ are directly accessible without authentication via HTTP GET requests. These templates expose internal application logic, variable names, AJAX endpoint URLs, and admin panel structure. This vulnerability is fixed in 1.11.38. |
| Chamilo LMS is a learning management system. Prior to 1.11.38, any authenticated user with a REST API key can modify their own status field via the update_user_from_username endpoint. A student (status=5) can change their status to Teacher/CourseManager (status=1), gaining course creation and management privileges. This vulnerability is fixed in 1.11.38. |
| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, the default password reset mechanism generates tokens using sha1($email) with no random component, no expiration, and no rate limiting. An attacker who knows a user's email can compute the reset token and change the victim's password without authentication. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 1.11.38, the get_user_info_from_username REST API endpoint returns personal information (email, first name, last name, user ID, active status) of any user to any authenticated user, including students. There is no authorization check. This vulnerability is fixed in 1.11.38. |
| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, REST API keys are generated using md5(time() + (user_id * 5) - rand(10000, 10000)). The rand(10000, 10000) call always returns exactly 10000 (min == max), making the formula effectively md5(timestamp + user_id*5 - 10000). An attacker who knows a username and approximate key creation time can brute-force the API key. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 2.0.0-RC.3, any authenticated user (including ROLE_STUDENT) can enumerate all platform users and access personal information (email, phone, roles) via GET /api/users, including administrator accounts. This vulnerability is fixed in 2.0.0-RC.3. |
| Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, multiple files use simplexml_load_string() without XXE protection. With LIBXML_NOENT flag, arbitrary server files can be read. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. |
