CVE-2026-1531
Unknown Unknown - Not Provided
Insecure SSL Verification in foreman_kubevirt Enables MITM Attack

Publication date: 2026-02-02

Last updated on: 2026-03-27

Assigner: Red Hat, Inc.

Description
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.

Executive Summary

This vulnerability is a Man-in-the-Middle (MITM) flaw in the foreman_kubevirt component. When connecting to OpenShift, SSL verification is disabled by default if a Certificate Authority (CA) certificate is not explicitly set. This means that if no CA certificate is configured, an attacker who can intercept network traffic between Satellite and OpenShift can eavesdrop or alter sensitive information because the connection is not properly secured. [1]

Impact Analysis

This vulnerability can allow a remote attacker who can intercept 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 transmitted over the connection, potentially compromising confidentiality and integrity of data. [1]

Detection Guidance

This vulnerability can be detected by checking the foreman_kubevirt configuration for SSL verification settings. Specifically, verify if the 'kubevirt_verify_ssl' option is enabled and if a Certificate Authority (CA) certificate is explicitly set. Commands to inspect the configuration files or settings where foreman_kubevirt connects to OpenShift can help identify if SSL verification is disabled. For example, you can use commands like 'grep kubevirt_verify_ssl /path/to/config' or inspect the relevant configuration files to confirm if a CA certificate is set. Network monitoring tools can also be used to detect potential Man-in-the-Middle (MITM) attack patterns between Satellite and OpenShift. [1]

Mitigation Strategies

To mitigate this vulnerability immediately, explicitly set a Certificate Authority (CA) certificate in the foreman_kubevirt configuration to enable proper SSL verification. This prevents the system from disabling SSL verification by default and protects against Man-in-the-Middle (MITM) attacks. Since no patch or fixed version is currently available, configuring SSL verification correctly is the recommended mitigation. [1]

Compliance Impact

This vulnerability allows a Man-in-the-Middle (MITM) attack that could lead to the disclosure or alteration of sensitive information transmitted between Satellite and OpenShift. Such exposure or modification of sensitive data could result in non-compliance with data protection standards and regulations like GDPR and HIPAA, which require the protection of sensitive information in transit. Therefore, if exploited, this vulnerability may compromise compliance with these regulations. [1]
