burpeditor

Inspect and edit Burp Suite .burp project files from the command line, without Burp.

Installation

pipx install burpeditor

Editing history items

Commands that modify a project overwrite it; use -o/--output new.burp to save the result to a new file and keep the original. Close the project in Burp first.

# Open the request in $EDITOR (the response with --response)
burpeditor edit project.burp 12
burpeditor edit project.burp 12 --response

# Replace messages with files, saving to a new project
burpeditor edit project.burp 12 --request-file request.txt --response-file response.txt -o edited.burp

By default the new message replaces the original one (and any auto-modified or edited versions), so Burp shows it directly. With --keep-original it is stored the way Burp stores a message changed in the interceptor: Burp keeps the original and offers both in the message viewer (Original/Edited). Item metadata that Burp derives from the messages (method, URL, host, extension, parameters, status, MIME type, length, title, cookies) is updated too; the site map is not. Line endings are normalized to CRLF, and a request with a body but no Content-Length gets one; an existing Content-Length is kept as written.

import reads the XML that Burp writes with "Save items" (Proxy history, site map, ...) and adds every item to the new project's HTTP history, keeping the host, port, protocol, IP, time and comment of each item. The export only has second precision for times.

New items can be added to the history with burpeditor add project.burp --request-file req.txt [--response-file resp.txt] [--http].

How it works

A .burp file is a memory-mapped object heap with a bump allocator. Objects are records (flags, type, schema version, field count, field descriptors, values) and primitive arrays, linked by absolute 64-bit offsets. burpeditor reads that object graph directly, and writes by allocating new objects at the end of the heap and updating pointers, as Burp does. burpeditor/burp/store.py documents the layout.

create writes the objects Burp allocates for a new project (the application root, its tools and the default project options), taken from a real project with all data collections and identifiers removed, and then fills in fresh empty collections, random identifiers and the project name.

Files are written in format version 222; newer Burp versions upgrade them when the project is opened. Projects created or edited by burpeditor have not been verified against every Burp release, so keep a copy of anything important.
