A flaw was found in foreman_kubevirt. When configuring the connection to OpenShift, the system disables SSL verification if a Certificate Authority (CA) certificate is not explicitly set. This insecure default allows a remote attacker, capable of intercepting network traffic between Satellite and OpenShift, to perform a Man-in-the-Middle (MITM) attack. Such an attack could lead to the disclosure or alteration of sensitive information.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:5968 advisory.

    Red Hat Satellite is a system management solution that allows organizations     to configure and maintain their systems without the necessity to provide     public Internet access to their servers or other client systems. It     performs provisioning and configuration management of predefined standard     operating environments.

    Security Fix(es):

    * yggdrasil-worker-forwarder: Memory exhaustion in query parameter parsing in net/url (CVE-2025-61726)
    * yggdrasil-worker-forwarder: golang: Denial of Service due to excessive resource consumption via crafted     certificate (CVE-2025-61729)
    * yggdrasil-worker-forwarder: Unexpected session resumption in crypto/tls (CVE-2025-68121)
    * rubygem-rubyipmi: Remote Code Execution in rubyipmi via malicious BMC username (CVE-2026-0980)
    * rubygem-foreman_kubevirt: foreman_kubevirt: Man-in-the-Middle due to insecure default SSL verification     (CVE-2026-1531)
    * foreman: Foreman: Remote Code Execution via command injection in WebSocket proxy (CVE-2026-1961)
    * rubygem-katello: Katello: Denial of Service and potential information disclosure via SQL injection     (CVE-2026-4324)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
