Never Let Okta or Entra ID Cert Rollovers
Break Production SSO.

Free mock IdPs only test happy-path logins. SAML Chaos Lab acts as an adversarial Identity Provider, injecting dual-key rollovers, XML signature wrapping (XSW), expired assertions, and replay attacks directly into your Service Provider ACS before Fortune 500 enterprise rollouts.

SECURE SP EXPECTATION PASS (200 OK)

SP keystore caches multiple signing keys; verifies assertion via rotated secondary cert without dropped sessions.

COMMON PRODUCTION DEFECT 500 OUTAGE

SP only stores the primary cert in config. Valid rotation triggers 'Signature verification failed' — company-wide SSO lockout.

ALG: RSA-SHA256

DIGEST: SHA-256

KEY_ID: KEY-SEC-2026-B

CLOCK_DRIFT: 0.00s (NOMINAL)

The Annual Cert Rollover Trap & Production SSO Blindspots

Standard staging environments only test happy-path logins with a static mock certificate. In enterprise production, identity providers like Okta, Microsoft Entra ID, and Ping Identity regularly roll signing keys or experience clock drift.

FAULT-VEC: CERT-01 SEV-1 OUTAGE

The Dual-Key Rollover Lockout

When an enterprise admin schedules a certificate rotation, Okta publishes a new certificate alongside the existing one. If your Service Provider code only binds to a single static string in an environment variable, every single user is locked out the millisecond the IdP switches the signing key.

Scenario: SAML-CERT-001 [Automated in Lab]

FAULT-VEC: REPLAY-04 PENTEST FINDING

Stateless Assertion Replay

SAML 2.0 assertions are valid for a temporal window (typically 5 minutes). If your ACS endpoint fails to index consumed Assertion IDs in a distributed TTL cache (such as Redis), an attacker or intercepted browser token can replay the exact same response and authenticate repeatedly.

Scenario: SAML-REPLAY-001 [Automated in Lab]

FAULT-VEC: XSW-03 CVSS 9.8 EXPLOIT

XML Signature Wrapping (XSW)

Naive XML parsing libraries verify the digital signature against one node in the XML DOM tree, but extract user attributes (like `admin: true` or `email`) from a different node. SAML Chaos Lab injects all 8 XSW variants to prove your parser is strictly anchored.

Scenario: SAML-XSW-001..008 [Automated in Lab]
