DDFFileParser in eclipse leshan is vulnerable to XXE Attacks
Summary
DDFFileParser in eclipse leshan is vulnerable to XXE Attacks
Original description
The description as published by the source.
Eclipse Leshan is a device management server and client Java implementation. In affected versions DDFFileParserandDefaultDDFFileValidator(and soObjectLoader) are vulnerable to XXE Attacks`. A DDF file is a LWM2M format used to store LWM2M object description. Leshan users are impacted only if they parse untrusted DDF files (e.g. if they let external users provide their own model), in that case they MUST upgrade to fixed version. If you parse only trusted DDF file and validate only with trusted xml schema, upgrading is not mandatory. This issue has been fixed in versions 1.5.0 and 2.0.0-M13. Users are advised to upgrade. There are no known workarounds for this vulnerability.
