SAMLReQuest

Summary: PortSwigger's BApp Store lists SAMLReQuest, a Burp Suite extension by Ahmad Abolhadid at version 2.1 that lets security testers view, decode, and modify SAML authentication requests and test an IdP's response to those manipulations. The listing describes SAML as the mechanism behind many single sign-on implementations, where a Service Provider redirects a user to an Identification Provider with a SAML authentication request, and rates the extension's overall system impact as High.

Key Takeaway: SAML underpins single sign-on across many Service Providers, and this tool exists to tamper with authentication requests and see how the IdP answers - the same manipulation an attacker would attempt against your SSO.
