Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-50187 is a critical remote code execution (RCE) vulnerability in Chamilo, an open-source learning management system. In versions prior to 1.11.28, a parameter from a SOAP request is evaluated without proper filtering, allowing arbitrary code injection. This flaw is categorized under CWE-95 (Improper Neutralization of Directives in Dynamically Evaluated Code) and has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting its high severity due to network accessibility and comprehensive impact on confidentiality, integrity, and availability.

The vulnerability can be exploited by any unauthenticated attacker with network access to the Chamilo instance. Exploitation requires low complexity and no user interaction, enabling the attacker to execute arbitrary code on the server, potentially leading to full system compromise, data theft, or further lateral movement within the environment.

Chamilo has patched this issue in version 1.11.28. Administrators are advised to upgrade immediately to mitigate the risk. Additional details are available in the GitHub security advisory (GHSA-356v-7xg2-3678) at https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-356v-7xg2-3678 and the release notes at https://github.com/chamilo/chamilo-lms/releases/tag/v1.11.28.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and code analysis can discover eval-injection flaws but does not stop their introduction.

Input validation explicitly requires neutralizing untrusted data before it reaches dynamic evaluation constructs such as eval.

Secure-development standards and tools can mandate safe coding patterns that avoid unsafe dynamic evaluation.

Application security requirements include rules against dynamic code execution of untrusted input.

prevents

Secure architecture principles discourage unsafe dynamic evaluation constructs.

prevents

Secure coding explicitly requires neutralization of input before dynamic evaluation, directly mitigating eval injection.

none

Separation of environments limits the blast radius if eval injection occurs in non-production.
