Short explanation

Snipe-IT before 8.5.0 contains a SAML assertion replay vulnerability due to a non-atomic nonce check in the SAML acs handler [S0]. Attackers can reuse captured assertions to obtain multiple authenticated sessions [S0].

Why does it matter?

This vulnerability allows attackers to reuse captured SAML assertions using concurrent requests, bypassing IdP-driven revocation to obtain multiple authorized sessions [S0].

What should be done?

  • Follow official vendor advisories [S0].
  • Apply available updates where applicable [S0].

Show the technical text from the sources

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.
