Summary

In Frappe Learning Management System (LMS) prior to 2.52.1, SCORMRenderer.render in lms/page_renderers.py constructs and opens a server-side path without confirming its real path remains within public/scorm. A remote attacker can read files outside the SCORM directory.

Risk Assessment

An attacker can read files accessible to the server process, potentially disclosing sensitive information such as configuration or credentials. This compromises system confidentiality.

Recommendation

Upgrade Frappe LMS to version 2.52.1 or later. Restrict server process permissions and verify that the SCORM renderer properly validates paths.

Original NVD description (English source)

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to version 2.52.1, a remote attacker can request a traversal path handled by SCORMRenderer.render in lms/page_renderers.py. The renderer constructs and opens a server-side path without first confirming that its real path remains within public/scorm, allowing files outside the SCORM directory to be read when they are accessible to the server process. This issue is fixed in version 2.52.1.
