This release considerably enhances the detection of blind injection vulnerabilities based on response diffing. Various Burp Scanner checks involve sending pairs of payloads (such as or 1=1 and or 1=2) and looking for a systematic difference in the resulting responses. Previously, Burp used a fuzzy diffing algorithm that analyzed the whole content of responses. This approach has various limitations that can lead to false negatives, such as:
  • Small variations that are insignificant in the context of the whole response content are liable not to trigger the fuzzy diffing threshold, despite being highly significant when their precise syntactic context is taken into account.
  • Situations where application responses vary due to non-deterministic or unrelated factors can lead to large variations that trigger the fuzzy diffing threshold for all payloads, thereby masking other variations that depend systematically on the supplied payload. 
Burp now uses a more granular diffing logic that takes into account all of the response attributes that were previously exposed in the analyzeResponseVariations API and used in our backslash powered scanning research. Variations are separately analyzed for attributes such as tag names, HTTP status code, line count, HTML comments, and many others. This granularity avoids the limitations described above and dramatically improves the accuracy of blind scan checks in many cases.

Additionally, several of the payloads used in diff-based scan checks have been enhanced to ensure that observed differences are indeed the result of injecting into the intended technology, rather than other input-dependent logic. For example, some web application firewalls (lamely) filter input that matches or N=N and cause a different response than is observed for or N=M. Burp's payloads are now intelligent enough to avoid false positives in situations like this.

The scan checks whose logic has improved include: SQL injection, LDAP injection, XPath injection, file path manipulation, User-agent-dependent response, X-forwarded-for-dependent response, and Referer-dependent-response.

We welcome feedback about the real-world performance of the new scanning logic, particularly in relation to false negatives or positives for diff-based injection issues.

Burp Proxy's generated per-host SSL certificates now include the site's commonName in the subjectAlternativeName extension. Apparently fallback to the commonName was deprecated by RFC2818 (in 2000), and browsers have recently decided to implement this.

Burp Collaborator server now has a configurable logging function that can be used for diagnostic purposes. See the Collaborator configuration file documentation for more details.

Various other minor fixes and enhancements have been made.

This release adds a new option to prevent project data being accumulated for out-of-scope items that pass through Burp Proxy.

It is common for users to configure their system-wide proxy settings to send all traffic through Burp, with the result that a large quantity of irrelevant requests and responses go through Burp Proxy, generated by OS components, other software, or unrelated browsing by the user. With the new feature, you can prevent out-of-scope items being added to the Proxy history or Target site map, or being automatically sent to other Burp tools (such as for live scanning).

The new option can be turned on at Proxy / Options / Miscellaneous:
When you first add an item to scope, Burp will ask if you want to enable this option, to prevent the Proxy from sending out-of-scope items to the history or other Burp tools:

If you check "always take the same action in future", then Burp will remember your choice and apply it automatically on future executions of Burp, when you first add an item to scope. You can control the use of this setting, and whether the dialog is shown, at User options / Misc / Proxy history logging:

A large number of minor bugfixes and other enhancements have also been made.

This release adds various new features and addresses some issues.

There is a new Scanner check for suspicious input transformation. This issue arises when an application receives user input, transforms it in some way, and then performs further processing on the result. Burp reports reflected and stored input that has been transformed in the following ways:
  • Overlong UTF-8 sequences are decoded.
  • Invalid UTF-8 sequences containing illegal continuation bytes are decoded.
  • Superfluous (or "double") URL-encoded sequences are decoded.
  • HTML-encoded sequences are decoded.
  • Backslash escape sequences are unescaped.
  • Unexpected transformations resulting from submitting any of the above payloads.
Performing these input transformations does not constitute a vulnerability in its own right, but might lead to problems in conjunction with other application behaviors. An attacker might be able to bypass input filters by suitably encoding their payloads, if the input is decoded after the input filters have been applied. Or an attacker might be able to interfere with other data that is concatenated onto their input, by finishing their input with the start of a multi-character encoding or escape sequence, the transformation of which will consume the start of the following data.

Various enhancements have been made to Burp Infiltrator, in response to feedback from real-world usage:
  • A bug affecting the patcher when running on Java 6 or earlier has been fixed.
  • A bug that caused the manifest files of some nested JAR files to be lost has been fixed.
  • A bug that left invalid signatures in place after the relevant bytecode was modified has been fixed
Burp Scanner's issues are now mapped to CWE vulnerabilities.

There is a new command-line option to prevent Burp from pausing the Spider and Scanner when reopening existing projects. To prevent this, add the following argument to the command to launch Burp:


Various other enhancements and bugfixes have been made.

This release adds various enhancements and fixes:
  • There is a new command-line option to launch Burp with a specified user configuration file:


    This can be used to set any user-level option, including Burp extensions to load. It is useful when running Burp on headless systems where there is no UI for configuring user-level options. By creating a suitable user-level config file, it is possible to launch Burp on a headless system with specific Burp extensions or any other user-level setting.
  • Some recent changes to Tomcat cause it to reject a wider range of raw characters in the URL query string, going beyond the standard practice of browsers and other web servers. Burp Scanner and Intruder now apply URL-encoding to the relevant characters by default, ensuring that their payloads are accepted by Tomcat and reach the application code.
  • A bug that was recently introduced that prevented license activation in headless mode has been fixed.
  • The Content Discovery function now correctly handles applications that have wildcard behavior for file extensions (e.g. those that return a specific response for regardless of the file extension). This eliminates the only known false positives reported by the new Content Discovery engine.
  • There are some new options in the Proxy for stripping request headers that offer to support encodings that may cause problems with intercepted traffic in Burp. These options are on by default.
  • Logging options have moved from the user level to the project level, and are now included in project-level configuration files and project files. This means that you can enable logging on a per-project basis and have this setting remembered when reopening a project file.
  • Unicode characters in URLs are now properly handled in the "Paste URL as request" function.
  • Various other minor bugfixes and enhancements have been made.
