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.
The extension is divided in two parts. A SAML message editor and a certificate management tool.
Features of the SAML Raider message editor:
- Sign SAML Messages
- Sign SAML Assertions
- Remove Signatures
- Edit SAML Message (Supported Messages: SAMLRequest and SAMLResponse)
- Preview eight common XSW Attacks
- Execute eight common XSW Attacks
- Send certificate to SAMl Raider Certificate Management
- Undo all changes of a SAML Message
- Supported Profiles: SAML Webbrowser Single Sign-on Profile, Web Services Security SAML Token Profile
- Supported Bindings: POST Binding, Redirect Binding, SOAP Binding, URI Binding
Features of the SAML Raider Certificate Management:
- Import X.509 certificates (PEM and DER format)
- Import X.509 certificate chains
- Export X.509 certificates (PEM format)
- Delete imported X.509 certificates
- Display informations of X.509 certificates
- Import private keys (PKCD#8 in DER format and traditional RSA in PEM Format)
- Export private keys (traditional RSA Key PEM Format)
- Cloning X.509 certificates
- Cloning X.509 certificate chains
- Create new X.509 certificates
- Editing and self-sign existing X.509 certificates
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
Install button to install our extension.
Don't forget to rate our extension with as many stars you like
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

To start the Extension directly from Eclipse, import the Repository into
Eclipse. You can directly import a existing Maven Project. Note that the
Eclipse Maven Plugin
m2e is required. This is included in the latest "Eclipse

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
to Burp (
localhost:8080) and prints out the modified response from our
plugin. You have to install
