Summary

Snipe-IT before 8.5.0 allows SAML assertion replay because the nonce check in the SAML acs handler is not atomic. A remote attacker with low privileges who has captured a valid assertion can send concurrent POST requests to /saml/acs to obtain multiple authenticated victim sessions that evade IdP-driven revocation, as described in CWE-294.

Description from the CNA

Snipe-IT before 8.5.0 contains a SAML assertion replay vulnerability that allows attackers to reuse captured assertions by exploiting a non-atomic nonce check in the SAML acs handler. Attackers can send concurrent POST requests to /saml/acs with one captured assertion to obtain multiple authenticated victim sessions that evade IdP-driven revocation.
