 # Integration with Burp Suite active and passive scanner
 Java Deserialization Scanner uses custom payloads generated with a modified version of "ysoserial", tool created by frohoff and gebl, to detect Java deserialization vulnerabilities. The original tool (https://github.com/frohoff/ysoserial) generate payloads for the execution of commands on the system, using the Runtime.exec function. Usually, however, it is not possible to see the output of the command and consequently it is not simple to write a scanner based on this kind of function. For this reason, a modified version of ysoserial is used to generate different types of payloads, usefull for the detection of the issue instead of the exploitation:

-Furthermore, **URLSNDS payload has been introduced** to actively **detect Java deserialization without any vulnerable libraris**. If the plugin find only the URLDNS issue (and no vulnerable libraries), the attacker probably can execute DoS attacks but to achieve Remote Code Execution it is necessary more effort.
