Description Preview

Java Open Single Sign-On Project Home (JOSSO) is affected by a vulnerability that allows remote attackers to forge messages and bypass authentication by exploiting a weakness in SAML assertions. Specifically, the vulnerability arises when a SAML assertion lacks a Signature element, enabling attackers to craft malicious messages that can deceive the authentication mechanism. This type of attack is known as a "Signature exclusion attack" and can lead to unauthorized access to sensitive resources within the affected system.

Overview

This vulnerability in JOSSO enables remote attackers to manipulate SAML assertions to bypass authentication mechanisms, potentially leading to unauthorized access to protected resources. By exploiting the absence of a Signature element in SAML assertions, attackers can forge messages and deceive the system into granting unauthorized access.

Remediation

To mitigate this vulnerability, it is recommended to update the JOSSO implementation to a version that addresses the issue by ensuring that all SAML assertions include a valid Signature element. Additionally, organizations should monitor and validate incoming SAML assertions to detect and prevent potential exploitation of this vulnerability.
