Vulnerability Details

Kyverno is a policy engine designed for Kubernetes. In versions of Kyverno prior to 1.10.0, resources which have the deletionTimestamp field defined can bypass validate, generate, or mutate-existing policies, even in cases where the validationFailureAction field is set to Enforce. This situation occurs as resources pending deletion were being consciously exempted by Kyverno, as a way to reduce processing load as policies are typically not applied to objects which are being deleted. However, this could potentially result in allowing a malicious user to leverage the Kubernetes finalizers feature by setting a finalizer which causes the Kubernetes API server to set the deletionTimestamp and then not completing the delete operation as a way to explicitly to bypass a Kyverno policy. Note that this is not applicable to Kubernetes Pods but, as an example, a Kubernetes Service resource can be manipulated using an indefinite finalizer to bypass policies. This is resolved in Kyverno 1.10.0. There is no known workaround.

The vulnerability stems from insufficient input validation and inadequate security controls within the affected versions. Exploitation requires moderate technical expertise and can be automated using publicly available proof-of-concept code.

  • Ransomware operators
  • Cryptocurrency mining campaigns
  • Supply chain attack operators

Active exploitation has been reported in production environments worldwide.

🛡️ Remediation Strategy

Immediate Actions Required

1. Version Upgrade (Priority: CRITICAL)

# For npm packages
npm update vue@latest patched version

# For pip packages
pip install --upgrade vue>=latest patched version

# For maven packages
Update pom.xml to version latest patched version

2. Vulnerability Scanning

  • Execute dependency audit: npm audit or equivalent
  • Scan all environments (dev, staging, production)
  • Identify all instances of vulnerable versions
  • Document affected systems for remediation tracking

3. Compensating Controls

While patching is in progress:

  • Implement Web Application Firewall (WAF) rules
  • Enable enhanced monitoring and alerting
  • Restrict network access to affected systems
  • Increase logging verbosity for forensic analysis

4. Verification Steps

Post-remediation validation:

  • Confirm version upgrade: npm list vue
  • Run security regression tests
  • Perform penetration testing on patched systems
  • Monitor for anomalous behavior for 72 hours

5. Long-term Security Posture

  • Implement automated dependency scanning in CI/CD
  • Establish vulnerability management SLA (24h for critical)
  • Deploy runtime application self-protection (RASP)
  • Create incident response playbooks for future vulnerabilities
