Replicator

Replicator is a Burp Suite extension that helps developers to reproduce issues discovered by pentesters. The pentester produces a Replicator file
which contains the findings in the report. Each finding includes a request, associated session rules or macros, and logic to detect presence of the vulnerability. The tester sends the Replicator file to the client alongside the report. Developers can then open the file within Burp and replicate the issues. When vulnerabilities have been fixed, Replicator provides confirmation that the attack vector used in the pentest is now blocked. A retest is still recommended, in case alternative attack vectors remain exploitable.
