An XML External Entity (XXE) vulnerability exists in multiple WSO2 products due to improper configuration of the XML parser. The application parses user-supplied XML without applying sufficient restrictions, allowing resolution of external entities.
A successful attack could enable a remote, unauthenticated attacker to read sensitive files from the servers filesystem or perform denial-of-service (DoS) attacks that render affected services unavailable.
Weakness
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
