  • Burp scanner: how to add support for csrf tokens

    I'm having an issue with the Burp Scanner: when anti-csrf tokens are present, it seems the scanner cannot handle it and it faild to perform active/passive scans. Would it be possible through Burp Extension capabilities to add a feature so Burp checks each requests, extracts the CSRF token, and adds it to the submittion request? Thanks,

Header value: 1; mode=block My response contains this header: X-XSS-Protection: 1; mode=block As far as I know, that is a correct header?

  • Why Burp asks to activate license when starting by cmd.exe

    Hi all, I met a problem with Burp. I developed a java extension to launch burp in cmd.exe. I wrote a .bat file and call it by Java Runtime. It asks me to activate the license again. If I open the .bat file directly, it won't ask for activation. But if I open the .bat file by Java Runtime object like this: Runtime runtime = Runtime.getRuntime(); runtime.exec("cmd /k start...

  • Forcing Burp to open w/ scanner unpaused?

    Is is possible to force Burp to open in a state which scans are forcibly unpaused? I'm working on a project where we call doActiveScans() to a single entry from getProxyHistory(), and upon clicking on the "Scanner" tab, the scans in queue are marked as "waiting".

For the life of me I can't figure out how to get this configured correctly in Eclipse, even though I see some extensions in the bapp store actually do this.

  • Spider treating active scan URLs with injected parameter queries as new urls to spider.

    I built an extension that successfully spiders the application, but I have a problem where when active scanning starts in earnest, eventually it starts adding injected URLs into the scanning scope, thus duplicated the amount of work that needs to be done. I cannot find a configuration to shut off the behavior of identifying a URL with query params as a unique URL. I know that OWASP's ZA...
