**Name of the Vulnerable Software and Affected Versions** Apache Ambari versions prior to 2.1.2 **Description** The issue allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the `targetURI` parameter. This can be exploited by including a malicious URL in the `targetURI` parameter, potentially leading to phishing attacks. **Recommendations** For versions prior to 2.1.2, update to version 2.1.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the `targetURI` parameter to minimize the risk of exploitation.
