Description The issue allows for XML injection, which can lead to remote code execution. This is achieved by using a specific substring: "<file type='file' name='../" in an API request.

Recommendations For DedeCMS version 5.7 SP2, as a temporary workaround, consider restricting access to XML processing functions until a patch is available. Avoid using the name parameter in XML requests that could lead to directory traversal, such as '../', until the issue is resolved.
