Published: 02 March 2026
Summary
CVE-2025-50194 is a high-severity OS Command Injection (CWE-78) vulnerability in Chamilo Chamilo Lms. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 26.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-50194 is an OS Command Injection vulnerability (CWE-78) in Chamilo, an open-source learning management system. The flaw affects versions prior to 1.11.30 and resides in the file /main/cron/lang/check_parse_lang.php, where insufficient input validation allows attackers to inject and execute arbitrary operating system commands.
The vulnerability has 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), indicating network accessibility with low complexity but requiring high privileges. An authenticated user with elevated permissions, such as an administrator, can exploit this to execute arbitrary OS commands on the underlying server, potentially leading to full system compromise with high impacts on confidentiality, integrity, and availability.
The issue has been addressed in Chamilo version 1.11.30, as detailed in the project's GitHub security advisory (GHSA-xrr6-wv8p-5v3p), release notes, and the patching commit. Security practitioners should upgrade to the fixed version and review access controls for the affected cron endpoint to mitigate risks.

Why these techniques?
OS command injection in a web-accessible endpoint directly enables arbitrary command execution via T1059 (Command and Scripting Interpreter) and exploitation of a public-facing application via T1190.

Directly requires validation of inputs to the check_parse_lang.php script, blocking the unsanitized data that enables OS command injection.
Mandates timely application of the vendor patch (v1.11.30) that eliminates the command-injection flaw in the cron endpoint.
Enforces access restrictions on the /main/cron/lang/ path so that only authorized administrators can reach the vulnerable script.
