This release adds various minor enhancements:
  • There is a new hotkey for adding an Intruder payload position marker. This is not mapped to any keystroke by default, but this can be done at User options / Misc / Hotkeys.
  • There is a new option on startup to disable extensions. This can help resolve situations where a misbehaving extension causes problems during startup.
  • Burp Collaborator server now responds to DNS lookups containing the subdomain "spoofed" with the IP address This is to prevent the Collaborator being wrongly incriminated when a server being scanned is vulnerable to client IP spoofing, as happened here.
  • The option to strip the "Accept-Encoding" header in incoming requests to the Proxy has been modified so that it normalizes the header to a default value rather than stripping it altogether. The previous behavior caused problems with some WAFs configured to drop requests without this header.
  • The default max heap size requested by the platform installer has been reduced from 75% to 50% of total physical memory, in order to prevent OS performance issues on some platforms. This can be modified after installation by editing the vmoptions file in the installation directory.
  • MacOS App Nap has been disabled as this can cause Burp's automated activity (like scanning) to be suspended when the Burp window is in the background.
Additionally, a number of bugs have been fixed:
  • A bug that caused temporary data saved by Burp extensions and the sessions tracer to actually get stored in project files.
  • A bug that caused the Spider not to honor the "Maximum parameterized requests per URL" setting.
  • A bug that caused some lightweight popups to have full window decoration on some Linux desktop managers.
  • A bug that incorrectly handled loading of IP addresses from file into the scope configuration UI.
  • A bug that prevented upstream SNI from working when proxying traffic through Burp from an Android emulator.
  • A bug that caused report generation to fail altogether when it encountered an incomplete issue due to project file corruption.

This release adds a number of new scan checks relating to file upload functionality.

Burp Scanner has always treated the contents of a file upload (within a multipart POST request) as a regular insertion point where payloads can be placed. In the new release, various additional checks are performed on the file upload:
  • Some new payloads are used to upload files in various formats, such as PDF, SVG, HTML, PHP, and SSI.
  • Where relevant, Burp now modifies the file extension and content-type fields in the upload request to reflect the type of file that is being uploaded, so as to maximize the chance that the application will handle the file in the desired way.
  • Both in-band and out-of-band techniques are used to detect vulnerabilities in the application's handling of uploaded files.
For example, Burp can now detect server-side rendering of uploaded PDF documents, by using some embedded PDF JavaScript to trigger a Burp Collaborator interaction when the document is rendered:

The new detection techniques all lead to new versions of existing issues, notably PHP code injection, SSI injection, reflected XSS, stored XSS, and external service interaction.

Note: Some updates have been made to Burp Collaborator server to support the new scan checks. People running private Collaborator servers should update these now. As usual, Burp will show an alert on startup if the configured Collaborator server is out of date, and you can use the Collaborator health check to determine this at any time.

A number of bugs are also fixed, including a recently introduced bug affecting NTLM authentication.
