Upstream source description

ILIAS versions before 9.22, 10.0 through 10.9, and 11.0 through 11.2 contain an arbitrary file read vulnerability in the SOAP addFile method that allows authenticated users to read server files by supplying crafted XML with COPY-mode imports. Attackers can construct absolute file paths through an unsandboxed import directory and retrieve sensitive files including configuration files containing database credentials and setup passwords.
