CVE-2025-11393

8.7 HIGH

📋 TL;DR

A misconfigured proxy in runtimes-inventory-rhel8-operator attaches cluster administrative credentials to all commands instead of only authorized reports. This allows any authenticated cluster user to execute commands with full administrator privileges, potentially compromising the entire Red Hat cluster configuration.

💻 Affected Systems

Products:
  • runtimes-inventory-rhel8-operator
Versions: All versions prior to the patched release
Operating Systems: Red Hat Enterprise Linux 8
Default Config Vulnerable: ⚠️ Yes
Notes: Affects Red Hat OpenShift environments using the vulnerable operator. Requires authenticated cluster access.

⚠️ 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 cluster takeover: attacker gains full administrative control, can modify configurations, deploy malicious workloads, exfiltrate sensitive data, or disrupt operations.

🟠

Likely Case

Unauthorized configuration changes, privilege escalation, deployment of unauthorized containers, or data access beyond user permissions.

🟢

If Mitigated

Limited impact if network segmentation, strict RBAC, and monitoring prevent exploitation attempts from reaching vulnerable components.

🌐 Internet-Facing: LOW
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Exploitation requires authenticated access to the cluster but is straightforward once access is obtained.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check RHSA-2025:23236 for specific patched version

Vendor Advisory: https://access.redhat.com/errata/RHSA-2025:23236

Restart Required: Yes

Instructions:

1. Update the runtimes-inventory-rhel8-operator via Red Hat OpenShift OperatorHub. 2. Apply the patch from RHSA-2025:23236. 3. Restart affected operator pods.

🔧 Temporary Workarounds

Restrict Operator Access

linux

Limit user access to the vulnerable operator using RBAC to reduce attack surface.

oc adm policy remove-cluster-role-from-group system:authenticated system:unauthenticated

Network Segmentation

all

Isolate the operator's network traffic to prevent unauthorized access.

🧯 If You Can't Patch

  • Implement strict RBAC controls to limit user permissions to minimum required.
  • Enable detailed auditing and monitoring for unauthorized command execution attempts.

🔍 How to Verify

Check if Vulnerable:

Check operator version: oc get csv -n openshift-operators | grep runtimes-inventory-rhel8-operator

Check Version:

oc get csv -n openshift-operators | grep runtimes-inventory-rhel8-operator

Verify Fix Applied:

Verify operator version matches patched release from RHSA-2025:23236 and test that standard users cannot execute administrative commands.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized command execution logs from the operator proxy
  • Unexpected administrative actions from non-admin users

Network Indicators:

  • Unusual traffic patterns to management endpoints from standard user accounts

SIEM Query:

source="openshift-audit.log" AND user!="system:admin" AND verb IN ("create","update","delete","patch") AND resource="*"
