Java Serialized Payloads

This extension generates various Java serialized payloads designed to execute OS commands. There are three ways to use the extension:

  • Generate a payload from the Java Serialized Payloads Tab. You can then copy and paste it into other tabs in Burp.

  • Generate a payload from the Java Serialized Payloads Tab. In another tab you can select the text you want to replace and right click. You have three encoding options:

    • Raw - This will replace your selected text with a raw unencoded version of the payload.
    • B64 - This will replace your selected text with a Base64 encoded version.
    • URLEnc - This will replace your selected text with a URL-encoded and base64 encoded payload.

  • You can use inline commands to replace your text with a payload that contains your command. For example you can enter text in Repeater like:

    $(CC1|ping -c1

    Select the above text and right click any of the Java Serialized Payload Options and it will replace your command with a payload containing that command.

    The first parameter before the pipe in the above statement is the version of the exploit. You can enter any of the following:

    • CC1 or CollectionCommons1
    • CC2 or CollectionCommons2
    • GV1 or Groovy1
    • SP1 or Spring1

    TThe second parameter is the OS command you wish to run.
