Intruder - Use another char (or string) for payload substitution (§)

Jeanderson | Last updated: May 09, 2023 01:49PM UTC

Is there any way to change the § character in intruder? My requests are failing in intruder because it strips all of the occurrences of the § character from the original requests. Disabling this behavior (automatic strip §) would be enough too, when you don't need payload substituion. Probably related: https://forum.portswigger.net/thread/some-content-characters-change-when-request-is-sent-to-intruder-1af54c39 Thank you.

Hi Could you tell me the version of Burp that you are currently using? Could you also explain how you are sending your request to Intruder? Are you pasting it in, or sending it from another tool?

Burp version is 2023.3.5. I use the burp to proxy the original request, then search the POST request in the HTTP history, right click it and then click "send to intruder". If I click "send to repeater", the request arrives on the repeater OK and this problem doesn't happen. If a copy and paste the request from history to intruder, then the burp app freezes. I think this happens because of the request size: almost 2MB.
