Chamilo LMS, an open-source learning management system widely used in educational and corporate environments, suffers from a critical SQL Injection vulnerability identified as CVE-2025-50188. This vulnerability exists in versions prior to 1.11.30 and is caused by improper neutralization of special elements in SQL commands (CWE-89). Specifically, the affected scripts /plugin/vchamilo/views/syncparams.php and /plugin/vchamilo/ajax/service.php fail to adequately validate the GET parameter 'value', allowing attackers to manipulate the SQL query logic by injecting arbitrary SQL statements. The vulnerability can be exploited remotely over the network without user interaction, but it requires the attacker to have high privileges (PR:H), indicating that some level of authenticated access or elevated permissions is necessary. The CVSS 4.0 base score is 7.0 (high), reflecting the significant impact on confidentiality, integrity, and availability of the database. Exploitation could lead to unauthorized data modification, potentially compromising the integrity of educational records, user data, or system configurations. No known exploits have been reported in the wild yet, but the vulnerability's nature and ease of exploitation make it a critical concern for organizations relying on Chamilo LMS. The vendor has patched the issue in version 1.11.30, and users are urged to update promptly to mitigate risk.

The SQL Injection vulnerability in Chamilo LMS can have severe consequences for organizations worldwide. Successful exploitation allows attackers to alter database queries, potentially leading to unauthorized data modification, corruption of educational content, user information theft, or even complete compromise of the LMS database. This undermines the integrity and availability of critical learning management data, which can disrupt educational services and damage organizational reputation. Given the LMS's role in managing sensitive academic and user data, the breach could also lead to compliance violations and legal liabilities. Organizations with large deployments of Chamilo LMS, especially in education and government sectors, face heightened risk. The requirement for high privileges to exploit somewhat limits the attack surface but does not eliminate the threat, especially if internal threat actors or compromised accounts are involved. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the vulnerability remains a significant risk until patched.

To mitigate this vulnerability, organizations should immediately upgrade all Chamilo LMS instances to version 1.11.30 or later, where the issue is patched. In addition to patching, organizations should conduct a thorough audit of user privileges to ensure that only trusted users have high-level access, reducing the risk of exploitation by insiders or compromised accounts. Implementing Web Application Firewalls (WAFs) with SQL Injection detection rules can provide an additional layer of defense by blocking suspicious input patterns targeting the vulnerable GET parameters. Regularly monitoring application logs for unusual database query patterns or errors related to the affected scripts can help detect attempted exploitation. Organizations should also review and harden their overall access controls and network segmentation to limit exposure of the LMS to untrusted networks. Finally, conducting security awareness training for administrators and users about the risks of privilege misuse and suspicious activity can further reduce risk.
