CyberRota Analysis
AI-GeneratedOpenAM versions prior to 16.1.1 are vulnerable due to improper deserialization of the AuthenticatorImpl object graph in the WebAuthnAuthentication process, which can be exploited if an attacker has previously written controlled data to a user attribute. This critical vulnerability allows for the execution of arbitrary code within the application server, posing significant risks to system integrity and confidentiality. Organizations using OpenAM for access management should prioritize upgrading to version 16.1.1 to mitigate this severe threat.

Original NVD Description
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, WebAuthnAuthentication loads a serialized AuthenticatorImpl object graph from the configured userAttribute through loadAuthenticators without an ObjectInputFilter. Exploitation requires the WebAuthn flow to be reachable and an attacker to have previously written controlled data to that attribute through delegated administration, provisioning, directory access, legacy REST self-registration, or unsafe configuration. When those non-default conditions hold, the data is deserialized before assertion verification and can execute a classpath gadget in the application server process. This issue is fixed in version 16.1.1.
