Default Config Vulnerable: ⚠️ Yes
Notes: All deployments with affected versions are vulnerable regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise through successful brute-force attacks leading to unauthorized access, data exfiltration, and service disruption.

🟠

Likely Case

Denial of service through authentication system exhaustion or credential harvesting through brute-force attempts.

🟢

If Mitigated

Limited impact with proper network segmentation, strong authentication policies, and monitoring in place.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires network access to authentication endpoints but no authentication credentials.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Apply IBM App Connect Enterprise 11.0.0.25 or later, or 12.0.12.0 or later

Vendor Advisory: https://www.ibm.com/support/pages/node/7108661

Restart Required: Yes

Instructions:

1. Download the latest fix pack from IBM Fix Central. 2. Apply the fix pack following IBM's installation guide. 3. Restart all affected App Connect Enterprise components. 4. Verify the fix by checking version numbers.

🔧 Temporary Workarounds

Network Access Control

all

Restrict network access to App Connect Enterprise authentication endpoints using firewalls or network segmentation.

Rate Limiting at Network Level

all

Implement rate limiting for authentication requests using network appliances or web application firewalls.

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate App Connect Enterprise from untrusted networks
  • Deploy web application firewall with rate limiting rules for authentication endpoints

🔍 How to Verify

Check if Vulnerable:

Check the installed version of IBM App Connect Enterprise using the product's administrative interface or version command.

Check Version:

Check product documentation for version verification commands specific to your deployment method.

Verify Fix Applied:

Verify the version is 11.0.0.25 or later, or 12.0.12.0 or later after applying patches.

📡 Detection & Monitoring

Log Indicators:

  • Excessive failed authentication attempts from single IP addresses
  • Unusual authentication patterns or spikes in authentication requests

Network Indicators:

  • High volume of authentication requests to App Connect Enterprise endpoints
  • Traffic patterns suggesting brute-force attempts

SIEM Query:

source="app_connect_enterprise" AND (event_type="authentication_failure" AND count > 10 per minute per source_ip)
