Description
Due to the improper configuration of XML parser, user-supplied XML is parsed without applying sufficient restrictions, enabling XML External Entity (XXE) resolution in multiple WSO2 Products.
A successful XXE attack could allow a remote, unauthenticated attacker to:
* Read sensitive files from the server’s filesystem.
* Perform denial-of-service (DoS) attacks, which can render the affected service unavailable.
