CVE-2025-2586

7.5 HIGH

📋 TL;DR

CVE-2025-2586 is an unauthenticated API request flooding vulnerability in OpenShift Lightspeed Service. Attackers can send repeated queries to non-existent endpoints, causing excessive resource consumption that degrades monitoring systems and potentially leads to service unavailability. All OpenShift deployments using Lightspeed Service are affected.

💻 Affected Systems

Products:
  • OpenShift Lightspeed Service
Versions: All versions prior to the patched release
Operating Systems: Linux-based OpenShift platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Affects all OpenShift deployments with Lightspeed Service enabled in default configurations.

⚠️ 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

Complete service unavailability due to resource exhaustion, impacting both application functionality and cluster stability across the entire OpenShift environment.

🟠

Likely Case

Degraded monitoring capabilities, increased disk usage, and potential performance issues affecting application reliability.

🟢

If Mitigated

Minimal impact with proper rate limiting and monitoring in place, though some resource consumption may still occur.

🌐 Internet-Facing: HIGH - Attackers can exploit this without authentication from external networks.
🏢 Internal Only: MEDIUM - Internal attackers or compromised systems could still exploit this, but network segmentation provides some protection.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires only basic HTTP request capabilities and no authentication.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Red Hat advisory for specific patched versions

Vendor Advisory: https://access.redhat.com/security/cve/CVE-2025-2586

Restart Required: Yes

Instructions:

1. Check Red Hat advisory for patched version. 2. Update OpenShift Lightspeed Service to patched version. 3. Restart affected services. 4. Verify fix implementation.

🔧 Temporary Workarounds

Implement API Rate Limiting

all

Configure rate limiting on API endpoints to prevent request flooding

# Configure rate limiting in OpenShift API gateway or ingress controller
# Example: oc annotate route <route-name> haproxy.router.openshift.io/rate-limit-connections=10

Network Access Controls

all

Restrict access to Lightspeed Service API endpoints

# Use OpenShift NetworkPolicy to restrict access
oc apply -f network-policy.yaml

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate Lightspeed Service
  • Deploy additional monitoring for unusual API request patterns and resource consumption

🔍 How to Verify

Check if Vulnerable:

Check OpenShift Lightspeed Service version against Red Hat advisory

Check Version:

oc get pods -n openshift-lightspeed -o jsonpath='{.items[*].spec.containers[*].image}'

Verify Fix Applied:

Verify patched version is installed and test API endpoint flooding no longer causes resource exhaustion

📡 Detection & Monitoring

Log Indicators:

  • High volume of 404 responses from API endpoints
  • Unusual increase in metrics storage writes
  • Resource consumption alerts for CPU/RAM/disk

Network Indicators:

  • High frequency requests to non-existent API endpoints
  • Unusual traffic patterns to Lightspeed Service

SIEM Query:

source="openshift-lightspeed" AND (response_code=404 AND request_count>1000) OR (resource_usage>90%)
