CVE-2026-1530
📋 TL;DR
A vulnerability in fog-kubevirt allows remote attackers to perform Man-in-the-Middle attacks by intercepting communications between Satellite and OpenShift due to disabled certificate validation. This can lead to interception and alteration of sensitive data. Systems using fog-kubevirt with vulnerable configurations are affected.
💻 Affected Systems
- fog-kubevirt
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all communications between Satellite and OpenShift, allowing attackers to steal credentials, inject malicious payloads, and manipulate cluster operations.
Likely Case
Interception of sensitive configuration data, authentication tokens, and deployment information leading to unauthorized access and data exposure.
If Mitigated
Limited impact with proper network segmentation and certificate validation enabled, though some risk remains from internal threats.
🎯 Exploit Status
MITM attacks require network positioning between Satellite and OpenShift; no authentication needed to intercept traffic when certificate validation is disabled.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisory for specific fixed versions
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2026-1530
Restart Required: Yes
Instructions:
1. Check Red Hat advisory for affected versions. 2. Update fog-kubevirt to patched version. 3. Restart affected services. 4. Verify certificate validation is enabled.
🔧 Temporary Workarounds
Enable Certificate Validation
linuxManually enable certificate validation in fog-kubevirt configuration to prevent MITM attacks
# Edit fog-kubevirt configuration to enable SSL certificate verification
# Set appropriate configuration parameter to enforce certificate validation
Network Segmentation
allIsolate Satellite-OpenShift communications to trusted network segments
# Configure firewall rules to restrict traffic between Satellite and OpenShift to specific IPs/ports
# Use VPN or private network for sensitive communications
🧯 If You Can't Patch
- Implement strict network controls to limit who can intercept Satellite-OpenShift traffic
- Monitor network traffic for unusual patterns indicating MITM activity
🔍 How to Verify
Check if Vulnerable:
Check fog-kubevirt configuration for disabled certificate validation; review version against Red Hat advisoryCheck Version:
rpm -q fog-kubevirt # or appropriate package manager commandVerify Fix Applied:
Verify fog-kubevirt is updated to patched version and certificate validation is enabled in configuration📡 Detection & Monitoring
Log Indicators:
