OpenAM (Open Source Edition) allows an attacker to bypass authentication and access unauthorized contents via unspecified vectors. Note that this vulnerability affects OpenAM (Open Source Edition) implementations configured as SAML 2.0IdP, and switches authentication methods based on AuthnContext requests sent from the service provider.
The Core Server in OpenAM 9.5.3 through 9.5.5, 10.0.0 through 10.0.2, 10.1.0-Xpress, and 11.0.0 through 11.0.2, when deployed on a multi-server network, allows remote authenticated users to cause a denial of service (infinite loop) via a crafted cookie in a request.
