Detailsinfo

A vulnerability was found in Red Hat Advanced Cluster Management for Kubernetes (version now known). It has been declared as problematic. This vulnerability affects some unknown processing of the component Insights API URL Path. The manipulation of the argument ClusterID with an unknown input leads to a redirect vulnerability. The CWE definition for the vulnerability is CWE-601. A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks. As an impact it is known to affect integrity. CVE summarizes:

A flaw was found in insights-client. A compromised managed cluster, referred to as a 'spoke', can inject unencoded data into the Insights API URL path. This occurs because the ClusterID, which is controlled by the spoke, is used directly in the request path without proper validation or URL encoding. This vulnerability allows a malicious spoke to redirect authenticated requests to unintended API endpoints, potentially leading to information disclosure or unauthorized access.
