Vulnerability details
Casdoor versions 2.362.0 and earlier map SAML assertions to user sessions without replay protection. The ParseSamlResponse() function in object/saml_sp.go calls sp.RetrieveAssertionInfo() and immediately maps the result to a user session. There is no assertion ID cache, OneTimeUse condition enforcement, or…
more
replay detection anywhere in the SAML SP code path. As a result, an attacker can replay a previously captured SAML assertion to obtain an authenticated session for the assertion’s subject, including administrator accounts, without needing the user’s password or MFA credentials.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Allows detection of capture-replay attacks by showing the replayed logon's timestamp as the last logon.
Protects against replay of captured session tokens or credentials by requiring authenticated, fresh session channels.
Wireless link protections commonly incorporate replay protection, reducing the exploitability of capture-replay weaknesses.
Accurate synchronized time enables tight timestamp windows that directly limit capture-replay windows in authentication protocols.
