Summary
OpenAM up to version 14.7.2 does not properly validate the signature of SAML responses in the SSO process, allowing attackers to impersonate any OpenAM user, including the administrator.
Risk Assessment
The organization may be exposed to attacks that allow unauthorized access to systems and data, potentially leading to serious security breaches.
Recommendation
It is recommended to upgrade OpenAM to version 14.7.3-SNAPSHOT or later. If upgrading is not possible, comment out the `SAMLPOSTProfileServlet` in the pom file.

Original NVD description (English source)
Open Access Management (OpenAM) is an access management solution that includes Authentication, SSO, Authorization, Federation, Entitlements and Web Services Security. OpenAM up to version 14.7.2 does not properly validate the signature of SAML responses received as part of the SAMLv1.x Single Sign-On process. Attackers can use this fact to impersonate any OpenAM user, including the administrator, by sending a specially crafted SAML response to the SAMLPOSTProfileServlet servlet. This problem has been patched in OpenAM 14.7.3-SNAPSHOT and later. User unable to upgrade should comment servlet `SAMLPOSTProfileServlet` from their pom file. See the linked GHSA for details.
