Description

Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, multiple files use simplexml_load_string() without XXE protection. With LIBXML_NOENT flag, arbitrary server files can be read. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.

Analysis

Chamilo LMS versions prior to 1.11.38 and 2.0.0-RC.3 allow authenticated attackers to read arbitrary server files through XML External Entity (XXE) injection via improper use of simplexml_load_string() with the LIBXML_NOENT flag enabled across multiple application files. The vulnerability requires low-privilege authentication and medium attack complexity but grants high confidentiality impact with no integrity or availability impact; no public exploit code or active exploitation has been identified at the time of analysis.
