1.7.13

This release adds various enhancements and bugfixes.

Burp Infiltrator has been enhanced with a large number of new API sink definitions, for both the Java and .NET platforms. This dramatically increases the coverage of existing vulnerabilities, such as OS command injection and file path traversal.

You can export the updated Infiltrator installers from the "Burp" menu in Burp Suite Professional. If you have already installed an earlier version of Infiltrator in an application, you can just run the new installer to update the instrumentation with the new API sink definitions.

The BurpInfiltrator.dll .NET assembly is now signed, and all instrumented assemblies refer to it by its strong name. This change will address some issues that can arise with usage of signed assemblies.

The manual Burp Collaborator client has been enhanced to give full details of Infiltrator interactions. This can greatly assist manual testing and exploitation of vulnerabilities, for example by showing the full SQL query that is executed when some particular input is submitted. Also, the Collaborator client UI now shows the Collaborator payload in the table of interactions, and supports user comments and highlights:



The IBurpCollaboratorClientContext API now supports separate retrieval of regular Collaborator interactions and Infiltrator-driven interactions.

The following bugs have been fixed:
  • A bug in the "copy as curl command" function which could enable a malicious website to generate an HTTP request which, if the Burp user uses the "copy as curl command" function and executes the output in a shell context, will cause arbitrary commands to be executed. There is no exposure to users who do not use the "copy as curl command" function, but it is recommended that all users upgrade to the latest version. This issue was discovered through an internal security review, rather than a user report.
  • A bug in the Burp Collaborator health check which caused SMTP/S connections made by the health check not to honor the configured SOCKS proxy settings.
  • A bug which caused Proxy match/replace rules to display as type "regex" even if they are not.
  • A bug where use of a partial/incomplete configuration file at project startup caused any undefined configuration options to have blank values. Now, any undefined options are assigned their default values.
  • A bug which caused Burp to leave temporary files on disk if the user cancels out of the project startup wizard.
  • A bug which caused items in the active scan queue in the "waiting to cancel" state to display in that state indefinitely if the project is closed and reopened.

1.7.12

This release updates the Burp Collaborator server to capture SMTP interactions, and adds two new related checks to Burp Scanner.

There is a new scan check for SMTP external service interaction. This reports an informational issue that identifies application functions that can be used to generate an email to an arbitrary address. This will typically (though not always) be intended application behavior, but it represents interesting attack surface for manual review:



There is a new scan check for SMTP header injection. This reports cases where it is possible to inject email headers, with the result that an email generated by the application is copied to an arbitrary email address:



For all SMTP-related issues, Burp Collaborator captures the full SMTP conversation that took place, and this is reported within the scan issue. This provides evidence for the issue itself, and also may contain interesting information about the technologies and infrastructure being used:





Note that users who have deployed a private Burp Collaborator server will need to upgrade their deployment to use the latest version, to gain the benefit of the new SMTP capabilities.

1.7.11

This release adds support for the .NET platform in the Burp Infiltrator tool.



To use Burp Infiltrator on .NET applications, go to Burp menu / Burp Infiltrator, and select the .NET option in the export wizard. For more details, see the Burp Infiltrator documentation.

The new .NET version of Burp Infiltrator works in the same way as the existing Java version. It supports languages written in C#, VB, and any other .NET languages. It supports versions 2.0 and later of the .NET framework.

To patch .NET applications, Burp Infiltrator makes use of bytecode assembly and disassembly tools. These can be either: (a) the ilasm and ildasm tools that are distributed with the .NET framework and the Windows SDK tools, respectively; or (b) the ilasm and monodis tools that are distributed with mono. You must specify the location of the assembly and disassembly tools during the patching process. Note that the version of the assembly tool must match the version of the .NET framework that the bytecode is targeting, to ensure compatibility.

1.7.10

This release adds some new APIs that extensions can use to easily implement powerful scan checks and other logic that involves response diffing.

Two new APIs have been added to IExtensionHelpers. The method:

IResponseVariations analyzeResponseVariations(byte[]... responses)

analyzes a collection of responses to identify variations in a range of attributes. The IResponseVariations object that is returned can be queried to determine the invariant or variant attributes, and the "value" of each attribute for each response:

List<String> getVariantAttributes();
List<String> getInvariantAttributes();
int getAttributeValue(String attributeName, int responseIndex);

The attributes that are currently supported are as follows:

anchor_labels
button_submit_labels
canonical_link
comments
content_length
content_type
css_classes
div_ids
etag_header
first_header_tag
header_tags
initial_body_content
input_image_labels
input_submit_labels
last_modified_header
limited_body_content
line_count
outbound_edge_count
outbound_edge_tag_names
page_title
set_cookie_names
status_code
tag_ids
tag_names
visible_text
visible_word_count
whole_body_content
word_count

Note that all values are represented as integer numbers, and the values of some attributes are intrinsically meaningful (e.g. word count) while the values of others are less so (e.g. checksum of HTML tag names).

The method:

IResponseKeywords analyzeResponseKeywords(List<String> keywords, byte[]... responses)

analyzes a collection of responses to identify the number of occurrences of the specified keywords. The IResponseKeywords object that is returned can be queried to determine the keywords whose counts vary or do not vary, and the number of occurrences of each keyword for each response:

List<String> getVariantKeywords();
List<String> getInvariantKeywords();
int getKeywordCount(String keyword, int responseIndex);

The new APIs allow your extensions to let Burp handle the messy work of analyzing responses to determine if they are the same or different, and you can easily create powerful scan checks with some simple logic:
  1. Send novel payload.
  2. Ask Burp whether the response changed in some interesting respect.
  3. If so, report an issue.
On Friday, to coincide with our Backslash Powered Scanning talk at Black Hat EU, we will be releasing an extension to the BApp Store that demonstrates how the new APIs can be used to create powerful new scanning capabilities.
