CVE-2024-53349
📋 TL;DR
This vulnerability in Kuadrant v0.11.3 allows attackers to access service account tokens due to insecure permissions in the secrets component. Attackers can escalate privileges within the Kubernetes cluster by leveraging these tokens. Organizations running vulnerable Kuadrant versions in their Kubernetes environments are affected.
💻 Affected Systems
- Kuadrant
- Kuadrant Operator
📦 What is this software?
Kuadrant by Linuxfoundation
⚠️ Risk & Real-World Impact
Worst Case
Full cluster compromise where attackers gain administrative privileges, access all namespaces, deploy malicious workloads, exfiltrate sensitive data, and disrupt cluster operations.
Likely Case
Privilege escalation within the cluster allowing attackers to access sensitive resources, modify configurations, and potentially move laterally to other systems.
If Mitigated
Limited impact with proper network segmentation, RBAC restrictions, and monitoring detecting unauthorized token access attempts.
🎯 Exploit Status
Exploitation requires existing access to the Kubernetes cluster and knowledge of the vulnerable component. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.11.4 or later
Vendor Advisory: https://github.com/Kuadrant/kuadrant-operator
Restart Required: No
Instructions:
1. Update Kuadrant to version v0.11.4 or later using your package manager. 2. Verify the update completed successfully. 3. Monitor for any issues post-update.
🔧 Temporary Workarounds
Restrict Service Account Token Access
kubernetesApply RBAC policies to restrict access to service account tokens and secrets in the kuadrant namespace
kubectl create role restricted-secret-access --verb=get,list --resource=secrets --namespace=kuadrant
kubectl create rolebinding restrict-secrets --role=restricted-secret-access --serviceaccount=kuadrant:default --namespace=kuadrant
🧯 If You Can't Patch
- Implement strict network policies to isolate Kuadrant components from other cluster resources
- Enable audit logging for all secret access attempts and monitor for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check your Kuadrant version: kubectl get deployment kuadrant-controller -n kuadrant -o jsonpath='{.spec.template.spec.containers[0].image}'Check Version:
kubectl get deployment kuadrant-controller -n kuadrant -o jsonpath='{.spec.template.spec.containers[0].image}' | grep -o 'v[0-9.]*'Verify Fix Applied:
Verify the version is v0.11.4 or later and test that service account tokens are no longer accessible with default permissions📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to kuadrant namespace secrets
- Service account token usage from unexpected sources
- RBAC permission denied errors for secret access
Network Indicators:
- Unusual API server requests targeting kuadrant secrets
- Lateral movement from kuadrant namespace to other cluster resources
