Deeper analysisAI
CVE-2025-50191 is an error-based SQL injection vulnerability in Chamilo, an open-source learning management system. The flaw affects versions prior to 1.11.30 and is triggered through the POST parameter "userFile" in the /main/exercise/hotpotatoes.php script. Classified under CWE-89 with a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), it enables attackers to inject malicious SQL queries, potentially exposing or manipulating backend database contents.
Exploitation requires network access and high-privilege authentication (PR:H), such as administrative or teacher roles with access to the affected exercise module. Attackers face low complexity with no user interaction needed, allowing them to achieve high impacts on confidentiality, integrity, and availability. Successful exploitation could lead to unauthorized data extraction, modification, or deletion within the Chamilo database, potentially compromising sensitive user information, course data, or enabling further system escalation.
The vulnerability has been addressed in Chamilo version 1.11.30, as detailed in the project's GitHub security advisory (GHSA-82qx-25j7-5639), release notes, and the patching commit. Security practitioners should prioritize upgrading affected Chamilo instances to 1.11.30 or later to mitigate the issue, and review access controls on the hotpotatoes.php endpoint in the interim.
