CVE-2024-52284

7.7 HIGH

📋 TL;DR

This vulnerability allows users with GET or LIST permissions on BundleDeployment resources to retrieve Helm values containing sensitive credentials and secrets. It affects Kubernetes environments using BundleDeployment resources where Helm charts contain sensitive data in values. Any user with basic read permissions could potentially access secrets they shouldn't see.

💻 Affected Systems

Products:
  • Kubernetes BundleDeployment resources
  • Helm-based deployments
Versions: Specific versions not specified in references, but affects implementations where BundleDeployment resources expose Helm values
Operating Systems: Linux, Any OS running affected Kubernetes clusters
Default Config Vulnerable: ⚠️ Yes
Notes: Affects any Kubernetes environment using BundleDeployment resources where Helm charts contain sensitive values. The vulnerability exists in the permission model rather than specific software versions.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers gain access to production credentials, database passwords, API keys, and other secrets, leading to complete system compromise, data exfiltration, and lateral movement across the infrastructure.

🟠

Likely Case

Internal users or compromised accounts with standard permissions accidentally or intentionally access sensitive Helm values containing credentials, potentially leading to privilege escalation or data exposure.

🟢

If Mitigated

With proper RBAC controls limiting BundleDeployment access to trusted administrators only, the impact is minimal as only authorized personnel can access the sensitive data.

🌐 Internet-Facing: MEDIUM - While the vulnerability itself requires some level of access, if combined with other vulnerabilities or misconfigurations, internet-facing Kubernetes clusters could be at risk.
🏢 Internal Only: HIGH - Internal users with standard permissions pose significant risk as they can easily access sensitive credentials without needing special privileges.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires only GET or LIST permissions on BundleDeployment resources, which are often granted to regular users. The attack is simple: query BundleDeployment resources to extract Helm values.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisories for specific patched versions

Vendor Advisory: https://bugzilla.suse.com/show_bug.cgi?id=CVE-2024-52284

Restart Required: Yes

Instructions:

1. Review vendor advisory for specific patch versions
2. Update affected Kubernetes components or BundleDeployment implementations
3. Restart affected services
4. Verify permissions are properly restricted post-patch

🔧 Temporary Workarounds

Restrict BundleDeployment RBAC

linux

Immediately restrict GET and LIST permissions on BundleDeployment resources to only trusted administrators

kubectl create clusterrole restricted-bundle-deployment --verb=get,list --resource=bundledeployments
kubectl create clusterrolebinding admin-bundle-deployment --clusterrole=restricted-bundle-deployment --group=system:masters

Remove Sensitive Data from Helm Values

all

Move all credentials and secrets out of Helm values and into Kubernetes Secrets or external secret managers

# Review all Helm charts for sensitive values in values.yaml
# Migrate credentials to Kubernetes Secrets: kubectl create secret generic my-secret --from-literal=password=xxx
# Update Helm charts to reference secrets instead of inline values

🧯 If You Can't Patch

  • Implement strict RBAC controls to limit BundleDeployment access to essential personnel only
  • Audit all Helm values and remove any sensitive data, storing credentials in secure secret management systems

🔍 How to Verify

Check if Vulnerable:

Test if a user with only GET/LIST permissions on BundleDeployment can retrieve Helm values containing sensitive data: kubectl get bundledeployments -o yaml | grep -i secret

Check Version:

kubectl version && check specific BundleDeployment implementation version

Verify Fix Applied:

Verify that users without appropriate permissions cannot access BundleDeployment resources and that Helm values no longer contain plaintext credentials

📡 Detection & Monitoring

Log Indicators:

  • Unusual access patterns to BundleDeployment resources
  • Multiple GET requests to BundleDeployment endpoints from non-admin users
  • Audit logs showing users accessing bundledeployments resources

Network Indicators:

  • Increased API calls to /apis/*/bundledeployments endpoints
  • Traffic patterns suggesting data exfiltration from Kubernetes API

SIEM Query:

source="kubernetes-audit" AND resource="bundledeployments" AND (verb="get" OR verb="list") AND NOT user="system:serviceaccount:kube-system:*"
