Ac;ve Vulnerability Scanning<br />

Some Burp-Plugins ac;vely try to exploit subset of exis@ng gadgets<br />

Either blind through OOB communica@on ("superserial-ac@ve")<br />

For applica@ons running on JBoss<br />

Or @me-based blind via delay ("<strong>Java</strong> Deserializa@on Scanner")<br />

For gadgets in Apache Commons Collec@ons 3 & 4<br />

And gadgets in Spring 4<br />

Recommenda@on: Adjust ac@ve scanning payloads to not rely on<br />

specific gadgets - beEer use a generic delay introduc@on<br />

Such as "<strong>Serial</strong>DoS" (by Wouter Coekaerts), which is only HashSet based<br />

as of January 2015<br />
