  • Active Scanner Extension Incrementing Requests

    I have a custom active scanner extension which makes a finite number of requests via callbacks.makeHttpRequest(). This does not appear to increment the current active scan with the correct number of requests being made and stalls the scan status % given it does an 'unknown' number of requests. How does one tie into this to a) present the number of requests the plugin will make and b) inc...

  • sendToRepeater Fails to Set Tab Caption for First Request

    As the subject states, the first call to IBurpExtenderCallbacks.sendToRepeater() will not rename the numbered tab in the repeater to the last parameter (the tab caption string). Subsequent calls to sendToRepeater do set the tab caption properly, but the first call will not. It is particularly frustrating because Burp insists on having at least one request in the repeater, even if it is empty, s...

  • IScanIssue vs. IBurpCollaboratorInteraction

    Now that Extender plugins can use collaborator, it can be used to identify issues. The built-in active scanner can use this to attach the relevant interactions to the reported issue. Based on the IScanIssue interface, I can see no such method to implement for Extender plugins. Am I looking at the wrong place?

  • Extender API Parameters

    Hi! I'm developing an extension and I was wondering how can I get the vulnerable parameter for an issue. For example, in a Cross-site scripting as the one in the picture (, is there a method to get only the vulnerable parameter and not all of them? Also, is this documentation up to date?

    Hello, I am attempting to write my first burp extension in Python, but I found myself stuck at adding issues to the list of findings. Basically, my code is monitoring for new issues within newScanIssue(self, issue) in the BurpExtender() class, and performing some task based on the issue type, etc. This is working fine and the core function is implemented, however results are printed to the c...

  • Reduced parameters to be checked in Scanner

    I'm trying to write an extension of BURP to reduce the number of checks to be done while performing and Active/Passive scan. Our tool already provides integrity validation for links and non-editable data, so my idea was to create an extension so that the number of checks performed by BURP is reduced not to include those. I'm reviewing the API for extension but I cannot figure out if t...

  • Create extender jar using burpsuite.jar in classpath

    Hi, I had a question regarding the process for properly building (compiling and creating jar files) Java burp extensions. According to the normal process for this, the Extender interface files should be exported from within Burp in the Extender tab. Then the extension can be compiled and a jar file created using commands such as "javac -d build burp/" "jar -cf ex...
