Name of the Vulnerable Software and Affected Versions Chamilo versions prior to 1.11.14

Description The issue is related to a lack of protection in the SQL query structure, which can be exploited to impact the confidentiality, integrity, and availability of protected information. The searchField, filters, or filters2 parameter in the main/inc/ajax/model.ajax.php file is vulnerable to SQL Injection.

Recommendations For versions prior to 1.11.14, as a temporary workaround, consider restricting access to the main/inc/ajax/model.ajax.php file or disabling the searchField, filters, or filters2 parameter until a patch is available. Avoid using the searchField, filters, or filters2 parameter in the affected API endpoint until the issue is resolved.
