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 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.

A zip slip vulnerability in the file upload function of Chamilo v1.11 allows attackers to execute arbitrary code via a crafted Zip file.

Chamilo 1.11.16 is affected by an authenticated local file inclusion vulnerability which allows authenticated users with access to 'big file uploads' to copy/move files from anywhere in the file system into the web directory.

Chamilo is a learning management system. Chamillo is affected by a post-authentication phar unserialize which leads to a remote code execution (RCE) within versions 1.11.12 to 1.11.26. By abusing multiple supported features from the virtualization plugin vchamilo, the vulnerability allows an administrator to execute arbitrary code on the server. This issue has been patched in version 1.11.26.

Chamilo is a learning management system. Prior to version 1.11.30, a Stored XSS vulnerability exists in the glossary function, enabling all users with the Teachers role to inject JavaScript malicious code against the administrator. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.34, a Cross-Site Request Forgery (CSRF) vulnerability allows an attacker to delete projects inside a course without the victim’s consent. The issue arises because sensitive actions such as project deletion do not implement anti-CSRF protections (tokens) and GET based requests. As a result, an authenticated user (Trainer) can be tricked into executing this unwanted action by simply visiting a malicious page. This issue has been patched in version 1.11.34.

Chamilo version 1.11.40 and earlier are vulnerable to authenticated remote code execution in the main/inc/ajax/lang.ajax.php path. This endpoint is protected only by apiprotectcoursescript(true), which means any authenticated user enrolled in a course (student, teacher, DRH) can reach it.

Chamilo is a learning management system. Prior to version 1.11.30, there is an OS Command Injection vulnerability in /main/admin/sublanguageajax.inc.php via the POST newlanguage parameter. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.30, a logic vulnerability in the friend request workflow of Chamilo’s social network module allows an authenticated user to forcibly add any user as a friend by directly calling the AJAX endpoint. The attacker can bypass the normal flow of sending and accepting friend requests, and even add non-existent users. This breaks access control and social interaction logic, with potential privacy implications. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.30, the open parameter of help.php fails to properly sanitize user input. This allows an attacker to inject arbitrary HTML, such as underlined text, via a crafted URL. This issue has been patched in version 1.11.30.

Chamilo is a learning management system. Prior to version 1.11.30, there is a reflected cross-site scripting (XSS) vulnerability due to insufficient sanitization of the page parameter in the session/adduserstosession.php endpoint. This issue has been patched in version 1.11.30.
