CVE-2025-5417
📋 TL;DR
An insufficient access control vulnerability in Red Hat Developer Hub allows cluster admins/users with standard access to modify the rhdh/rhdh-hub-rhel9 container image content. This affects data confidentiality and integrity, though changes are not permanent as they reset after pod restarts. Only users with cluster and namespace access are affected.

⚠️ Risk & Real-World Impact
Worst Case
Malicious insider or compromised account modifies container image to inject malicious code, potentially leading to data exfiltration or further privilege escalation within the cluster.
Likely Case
Accidental or unauthorized modification of container image content causing service disruption or data integrity issues until pod restart.
If Mitigated
Minimal impact with proper access controls and monitoring; changes would be detected and automatically reverted on pod restart.
🎯 Exploit Status
Requires authenticated access to the cluster and namespace; changes are temporary and reset on pod restart

🔍 How to Verify
Check if Vulnerable:
Check if you're running an affected version of Red Hat Developer Hub using the rhdh/rhdh-hub-rhel9 container imageCheck Version:
oc get pods -n <namespace> -o jsonpath='{.items[*].spec.containers[*].image}' | grep rhdh-hub-rhel9Verify Fix Applied:
Verify the container image version matches the patched version in RHSA-2025:14090📡 Detection & Monitoring
