Key insight
Exploitation requires a malicious or compromised upstream IdP, or an IdP configuration that lets the user control the NameID , the attack vector therefore lies primarily in the federated identity chain, not at the perimeter.
Description
Fortinet FortiAuthenticator (versions 8.0.0 through 8.0.3 and 6.6.0 through 6.6.10) contains an improper neutralization of special elements in LDAP queries, enabling LDAP injection. An authenticated attacker can thereby bypass the authentication check. Successful exploitation additionally requires a malicious or compromised upstream identity provider, or an IdP configuration in which the user can control the NameID or the SAML attribute used as the username. The vendor has designated versions 8.0.4 and 6.6.11 as the fixed releases; at the time of publication there are no indications of active exploitation in the wild.
