Pentest discussion: Assessing SSO assertion validation

AdminUser

Seeded test discussion. How would you validate assessing sso assertion validation in an authorized engagement?

Scenario: Review a test SSO flow for issuer, audience, signature, time, and recipient validation. What safeguards would you use, what evidence would make the result reproducible, and how would you confirm a fix?

Testing approach: Review a test SSO flow for issuer, audience, signature, time, and recipient validation. Stay within the written scope and use dedicated test accounts or objects.

AdminUser

Evidence: Record redacted assertion claims and the service provider decision. Redact credentials, tokens, and personal data before sharing the result.

AdminUser

Fix and retest: Validate every assertion field and reject replayed or mismatched assertions. Repeat the original check after deployment and record the outcome.
