Professional 1.6.22
Summary: Burp Suite Professional 1.6.22, released 16 July 2015, adds a scan check for external service interaction and out-of-band resource load through injected XML doctype tags. The scanner sends payloads such as a DOCTYPE declaration pointing to a Burp Collaborator address and reports an issue based on any DNS or HTTP interactions that reach the Collaborator server.
Key Takeaway: The check targets XML external entity behavior that can make a server reach out to an attacker-chosen host, so a single injected doctype can turn a blind parser into an outbound connection from inside your network.
