SAML Raider - SAML2 Burp Extension
SAML Raider is a Burp Suite extension for testing SAML infrastructures. It contains two core functionalities: Manipulating SAML Messages and manage X.509 certificates.
This software was created by Roland Bischofberger and Emanuel Duss during a bachelor thesis at the Hochschule für Technik Rapperswil (HSR). Our project partner and advisor was Compass Security Schweiz AG . We thank Compass for the nice collaboration and support during our bachelor thesis.

Installation
Manual Installation
Start the Burp Suite and click at the
Extender tab on Add . Choose the SAML Raider JAR file to install the extension. Installation from BApp Store
The easy way to install SAML Raider is using the BApp Store. Open Burp and click in the
Extender tab on the BApp Store tab. Select SAML Raider and hit the Install button to install our extension. Don't forget to rate our extension with as many stars you like.
Usage
To test SAML environments more comfortable, you could add a intercept rule in the proxy settings. Add a new rule which checks if a Parameter Name
SAMLResponse is in the request. We hope the usage of our extension is mostly self explaining.Development
Build
Clone the repository and build the JAR file using Maven:
$ mvn install target/saml-raider-1.0-SNAPSHOT-jar-with-dependencies.jar as a Burp extension. Run SAML Raider inside Eclipse
To start the Extension directly from Eclipse, import the Repository into Eclipse. Note that the Eclipse Maven Plugin
m2e is required. Place the Burp Suite JAR file into the
lib folder and add the Burp JAR as a Library in the Eclipse Project ( Properties → Build Path → Libraries ). Open the Burp JAR under
Referenced Libraries in the Package Explorer and right click in the Package burp on StartBurp.class and select Run As... → Java Application to start Burp and load the Extension automatically. Debug Mode
To enable the Debug Mode, set the
DEBUG Flag in the Class Flags from the Package helpers to true . This will write all output to the SAMLRaiderDebug.log logfile and load example certificates for testing. Test with fake SAML Response
To send a SAML Response to Burp, you can use the script
samltest in the scripts/samltest directory. It sends the SAML Response from saml_response to Burp ( localhost:8080 ) and prints out the modified response from our plugin.
