Improvement in Burp Suite 2021.9

This new version let users allow to perform manual testing of the hidden HTTP/2 attack surface, which means users can send a HTTP/2 requests from Burp Repeater even if the server doesn’t explicitly advertise HTTP/2 support via ALPN.

In order to use this feature, Allow HTTP/2 ALPN override option from the Repeater menu then switch the protocol to HTTP/2 from the Inspector panel. Portswigger says.

Burp Intruder improvements

There are several improvements in the Burp Intruder through which users can eliminate duplicate entries when sending the payload to the target.

When using the Grep – Match or Grep – Payloads options, the results table now contains a column displaying the number of matches found in the response rather than just a checkbox.

New option for setting the delay between requests to an incremental value in the resource pool configuration.

New payloads

PortSwigger Also added new payloads to improve the scan check for server-side template injection to detect vulnerabilities.

Also, In Audit asynchronous traffic in Burp Scanner improved the way the crawler interacts with forms on a page to better support modern single-page applications.

“Burp Scanner can now handle iframes, multi-selects, scrolling elements, and SVG elements in recorded login sequences. We have also improved reliability of recorded logins by changing the way we locate and interact with elements on the page.” Burp Suite Said.
