Chamilo is a learning management system. Prior to version 1.11.28, parameter from SOAP request is evaluated without filtering which leads to Remote Code Execution. This issue has been patched in version 1.11.28.

Chamilo is a learning management system. Prior to version 1.11.30, there is a time-based SQL Injection in found in /main/webservices/registration.soap.php. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.30, there is an error-based SQL Injection via the GET openid.assochandle parameter with the /index.php script. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.30, in the application, deserialization of data is performed, the data can be spoofed. An attacker can create objects of arbitrary classes, as well as fully control their properties, and thus modify the logic of the web application's operation. This issue has been patched in version 1.11.30.

Chamilo LMS is a learning management system. Prior to version 1.11.34, there is an unauthenticated SQL injection vulnerability which allows remote attackers to execute arbitrary SQL commands via the customdates parameter. By chaining this with a predictable legacy password reset mechanism, an attacker can achieve full administrative account takeover without any prior credentials. The vulnerability also exposes the entire database, including PII and system configurations. This issue has been patched in version 1.11.34.

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 v1.11.x was discovered to contain a SQL injection via the doc parameter in main/plagiarism/compilatio/upload.php.

Chamilo LMS 1.11.8 and 2.x allows remote code execution through an lpupload.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 importpackage function, and extraction in $courseSysDir.$newDir.

Chamilo LMS version 11.x contains an Unserialization vulnerability in the "hash" GET parameter for the api endpoint located at /webservices/api/v2.php that can result in Unauthenticated remote code execution. This attack appear to be exploitable via a simple GET request to the api endpoint. This vulnerability appears to have been fixed in After commit 0de84700648f098c1fbf6b807dee28ec640efe62.

main/inc/ajax/model.ajax.php in Chamilo through 1.11.14 allows SQL Injection via the searchField, filters, or filters2 parameter.

Chamilo LMS v1.11.13 was discovered to contain a SQL injection vulnerability via the blogid parameter at /blog/blog.php.

A command injection vulnerability in the wsConvertPpt component of Chamilo v1.11. up to v1.11.18 allows attackers to execute arbitrary commands via a SOAP API call with a crafted PowerPoint name.

An arbitrary file upload vulnerability in the /fileUpload.lib.php component of Chamilo 1.11. up to v1.11.18 allows attackers to execute arbitrary code via uploading a crafted SVG file.

Command injection in /main/webservices/additionalwebservices.php in Chamilo LMS <= v1.11.20 allows unauthenticated attackers to obtain remote code execution via improper neutralisation of special characters. This is a bypass of CVE-2023-34960.

Improper sanitisation in main/inc/lib/fileUpload.lib.php in Chamilo LMS <= v1.11.20 on Windows and Apache installations allows unauthenticated attackers to bypass file upload security protections and obtain remote code execution via uploading of .htaccess file. This vulnerability may be exploited by privileged attackers or chained with unauthenticated arbitrary file write vulnerabilities, such as CVE-2023-3533, to achieve remote code execution.

Path traversal in file upload functionality in /main/webservices/additionalwebservices.php in Chamilo LMS <= v1.11.20 allows unauthenticated attackers to perform stored cross-site scripting attacks and obtain remote code execution via arbitrary file write.

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 versions 1.11.38 and earlier contain a stored cross-site scripting vulnerability in the user registration form that allows any unauthenticated attacker to execute arbitrary JavaScript in an administrator's browser session, leading to full platform admin account takeover. This has been patched in 1.11.40.

Chamilo is a learning management system. Prior to version 1.11.30, there is a blind SSRF vulnerability in /index.php via the POST openidurl parameter. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Versions prior to 1.11.34 have a Stored XSS through insecure file uploads in Social Networks. Through it, a low-privilege user can execute arbitrary code in the admin user inbox, allowing takeover of the admin account. Version 1.11.34 fixes the issue.

Chamilo is a learning management system. Prior to version 1.11.34, there is a stored cross-site scripting (XSS) vulnerability. By injecting malicious JavaScript into the course description field, an attacker with a low-privileged account (e.g., trainer) can execute arbitrary JavaScript code in the context of any other user viewing the course information page, including administrators. This allows an attacker to exfiltrate sensitive session cookies or tokens, resulting in account takeover (ATO) of higher-privileged users. This issue has been patched in version 1.11.34.

Chamilo is a learning management system. Prior to version 1.11.34, there is a stored cross-site scripting (XSS) vulnerability. By injecting malicious JavaScript into the course learning path Settings field, an attacker with a low-privileged account (e.g., trainer) can execute arbitrary JavaScript code in the context of any other user viewing the course information page, including administrators. This allows an attacker to exfiltrate sensitive session cookies or tokens, resulting in account takeover (ATO) of higher-privileged users. This issue has been patched in version 1.11.34.

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 moveto POST parameter — which only passes through Security::removeXSS() (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 (allowuserstocreatecourses = 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 is a learning management system. Prior to version 1.11.34, there is a stored XSS vulnerability in Chamilo LMS (Verison 1.11.32) allows an attacker to inject arbitrary JavaScript into the platform’s social network and internal messaging features. When viewed by an authenticated user (including administrators), the payload executes in their browser within the LMS context. This enables full account takeover via session hijacking, unauthorized actions with the victim’s privileges, exfiltration of sensitive data, and potential self-propagation to other users. This issue has been patched in version 1.11.34.

Chamilo LMS 1.11.26 is vulnerable to Incorrect Access Control via main/auth/profile. Non-admin users can manipulate sensitive profiles information, posing a significant risk to data integrity.

Chamilo LMS 1.11.8 contains an arbitrary file upload vulnerability that allows authenticated users to upload and execute PHP files through the elfinder filemanager module. Attackers can upload files with image headers in the social myfiles section, rename them to PHP extensions, and execute arbitrary code by accessing the uploaded files.

Chamilo is a learning management system. Prior to version 1.11.30, the application performs insufficient validation of data coming from the user from the POST resource[document][SQLINJECTIONHERE] and POST login parameters found in /main/coursecopy/copycoursesessionselected.php, which allows an attacker to perform an attack aimed at modifying the database query logic by injecting an arbitrary SQL statements. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.30, an input validation vulnerability exists when importing user data from CSV files. This flaw occurs due to insufficient sanitization of user data, specifically in the "Last Name", "First Name", and "Username" fields. It allows attackers to inject a stored cross-site scripting (XSS) payload that is triggered when the user profile is viewed, potentially leading to malicious script execution in the context of the authenticated use. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.30, Chamilo is vulnerable to deserialization of untrusted data in /plugin/vchamilo/views/import.php via POST configurationfile; POST coursepath; POST homepath parameters. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.34, Chamilo LMS is affected by an authenticated remote code execution vulnerability caused by improper validation of uploaded files. The application relies solely on MIME-type verification when handling file uploads and does not adequately validate file extensions or enforce safe server-side storage restrictions. As a result, an authenticated low-privileged user can upload a crafted file containing executable code and subsequently execute arbitrary commands on the server. This issue has been patched in version 1.11.34.
