    Hello All, I am working on a extension development which has a requirement for custom UI for intruder tab with default intruder functionalities (i.e. the ui is only different, core functionality will be same as intruder tab). Is it possible to override the intruder methods to create same functionality and display in my custom UI?

  • Extension - Closeable Tab UI element like in the Repeater

    I'm writing a Burp extension that has a UI and adds "closeable" tabs, exactly like in the Repeater tab, where there are small "x" to close a tab. However, mine look horrible, as I use a JButton (in Python): class CloseableTab(JPanel, ActionListener): def __init__(self, title, pyparent, content, customize_callback): self.title = title self.pyparent...

  • BurpSuite Professional 1.7.23 hangs during extensions loading

    Hi, After upgrading my Parallels Kali 2.0 VM from BurpSuite Pro 1.7.21 to 1.7.23 I noticed that whenever I want to install and load new extension BurpSuite hangs and enters something like deadloop. I tried few things (bigger -Xmx value, Oracle Java) but nothing helped so far. It occurs on fresh installation of BurpSuite Pro 1.7.23 without any extensions and without Jython/JRuby support.

  • Does not having BS Professional license impact Burp Extender?

    Question is quite specific enough, but to elaborate, I basically plan on writing something to visualize the sitemap better, and in a aesthetically-pleasing fashion. So obviously the only information I need access to would be the sitemap, *unimportant: eventually converted to JS object format with a style I've already created*. Anyways, back on topic... any limitations I need to watch out for...

  • Method to Pause/Unpause Scanner

    Does the API include methods for an extension to pause and unpause the scanner? I have searched the Javadocs but didn't find any. My scenario is an extension that implements ISessionHandlingAction to re-login the user when the session times out. I would like to pause the scanner while the login is happening so that it doesn't issue a bunch of requests with a stale session. Is the...

  • How do I highlight requests in a custom ITextEditor?

    I am writing a extension that adds a IMessageEditorTab to each request that displays a modified HTTP body. The base of the code is very similar to How do I get the ITextEditor to colorize the HTTP request the way it does in the raw tab?

  • SAXParser Dependency Delimma

    Hi guys, I'm in the process of writing a Burp extension in Python, and one of the dependency libraries makes use of the "xml.etree.cElementTree" module to parse XML markup. The problem is that any call to the "xml.etree.cElementTree.parse" function causes Jython to raise the following exception "java.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXPars...
