Probe endpoints consuming Java serialized objects for fingerprinting.
You just found a Java deserialization bug, you ran all your ysoserial payloads, and.... you got nothing. What now? How can you debug or build a gadget chain if you're totally blind?
Introducing GadgetProbe, a tool that shines a light on remote classpaths and raises bug severity for all!
GadgetProbe takes a wordlist of Java classes, outputs serialized DNS callback objects, and reports what's lurking in the remote classpath.
The Burp extension automatically integrates with Burp Collaborator to handle DNS callbacks. The extension also includes signatures and an analyzer to identify library versions of popular sources for gadgets.
