Summary

CVE-2025-50196 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 15% 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 map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2025-50196 is an OS Command Injection vulnerability (CWE-78) affecting Chamilo, an open-source learning management system. The flaw exists in versions prior to 1.11.30, specifically within the file /plugin/vchamilo/views/editinstance.php, where the POST main_database parameter fails to properly sanitize user input, allowing arbitrary operating system commands to be executed. The vulnerability was publicly disclosed on March 2, 2026, and carries 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), rated as High severity.

Exploitation requires high privileges (PR:H), such as those held by administrators or other privileged users with access to the affected endpoint over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). A successful attack enables remote code execution with high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged scope (S:U), potentially allowing full system compromise on the hosting server.

The issue has been addressed in Chamilo version 1.11.30, as detailed in the project's GitHub security advisory (GHSA-qfvp-xg47-m7m2) and release notes. Mitigation involves upgrading to the patched version, with relevant fixes implemented in commits afdbd4bb9a9ea17b7740559dd4e05aa13b16480d and e343c764493b457c82d1e85b91a3655b093767ed. Security practitioners should review access controls for the vchamilo plugin endpoint to limit exposure until patching is complete.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
