A pre-authentication remote code execution vulnerability affects OpenAM. The remote authentication endpoint (/authservice, PLL) accepts an XML element that names an arbitrary Java class, which the server then loads and instantiates without validation. On a default configuration this is reachable without authentication and allows an attacker to run code on the server.
Description An insufficient authorization (CWE-285) and information exposure (CWE-200) issue in OpenAM's session management endpoint allows a low-privileged authenticated user to retrieve active session credentials belonging to other users, including those with higher privileges. This affects OpenAM Community Edition through version 16.0.6 and was patched in version 16.1.1. This may be related to CVE-2021-4201, a similar issue patched in ForgeRock Access Management, a separate product sharing a common codebase ancestry.
OpenAM (Open Identity Platform) is an open-source Identity and Access Management (IAM) platform derived from ForgeRock OpenAM, providing SSO, OAuth2, SAML, and OpenID Connect capabilities. It is widely deployed in enterprise environments as a central authentication gateway. The /sessionservice endpoint, used for internal session management operations, does not sufficiently restrict the URLs that authenticated users may register for session event notifications. Under certain conditions, this may result in outbound server-side …
The NT auth module in OpenAM before 14.6.6 allows a "replace Samba username attack."
