CVE-2025-36085
📋 TL;DR
IBM Concert versions 1.0.0 through 2.0.0 contain a server-side request forgery (SSRF) vulnerability that allows authenticated attackers to make unauthorized requests from the server. This could enable network scanning, internal service enumeration, or facilitate other attacks by using the server as a proxy. Only authenticated users can exploit this vulnerability.
💻 Affected Systems
- IBM Concert
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attacker gains access to internal services, exfiltrates sensitive data, or uses the server as a pivot point for lateral movement within the network.
Likely Case
Network enumeration revealing internal infrastructure, potential data leakage from internal services accessible to the server.
If Mitigated
Limited impact due to network segmentation, egress filtering, and proper authentication controls.
🎯 Exploit Status
Requires authenticated access. Exploitation involves crafting malicious requests to trigger SSRF.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply the fix as specified in IBM Security Bulletin
Vendor Advisory: https://www.ibm.com/support/pages/node/7249356
Restart Required: No
Instructions:
1. Review IBM Security Bulletin. 2. Apply the recommended fix or upgrade to a patched version. 3. Verify the fix by testing SSRF attempts.
🔧 Temporary Workarounds
Network Segmentation
allRestrict outbound network access from IBM Concert servers to only necessary destinations.
Input Validation
allImplement strict input validation on all URL/request parameters used by the application.
🧯 If You Can't Patch
- Implement strict network egress filtering to limit outbound connections from IBM Concert servers.
- Enhance authentication monitoring and alert on suspicious authenticated user activity.
🔍 How to Verify
Check if Vulnerable:
Check IBM Concert version. If running 1.0.0 through 2.0.0, assume vulnerable.Check Version:
Check application version through administrative interface or configuration files.Verify Fix Applied:
Test SSRF attempts after applying patch. Attempts should be blocked or properly validated.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP/HTTPS requests from IBM Concert server
- Requests to internal IP addresses or unusual domains from application logs
Network Indicators:
- IBM Concert server making unexpected outbound connections to internal services
