CVE-2024-9408
📋 TL;DR
This CVE describes a Server-Side Request Forgery (SSRF) vulnerability in Eclipse GlassFish application server. Attackers can exploit specific endpoints to make the server send unauthorized requests to internal or external systems. Organizations running vulnerable versions of Eclipse GlassFish are affected.
💻 Affected Systems
- Eclipse GlassFish
📦 What is this software?
Glassfish by Eclipse
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of internal network resources, data exfiltration, or use as pivot point for further attacks on internal systems.
Likely Case
Unauthorized access to internal services, information disclosure from internal endpoints, or denial of service through resource exhaustion.
If Mitigated
Limited impact if network segmentation restricts GlassFish server's outbound connectivity and internal service access.
🎯 Exploit Status
SSRF vulnerabilities typically have low exploitation complexity once vulnerable endpoints are identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Eclipse GlassFish security advisories for specific patched version
Vendor Advisory: https://gitlab.eclipse.org/security/cve-assignement/-/issues/38
Restart Required: Yes
Instructions:
1. Check current GlassFish version. 2. Apply latest security patches from Eclipse. 3. Restart GlassFish server. 4. Verify patch application.
🔧 Temporary Workarounds
Endpoint Restriction
allRestrict access to vulnerable endpoints using web application firewall or reverse proxy rules
Network Segmentation
allLimit GlassFish server's outbound network connectivity to only required destinations
🧯 If You Can't Patch
- Implement strict network egress filtering to limit GlassFish server's outbound connections
- Deploy web application firewall with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check GlassFish version and compare against affected versions (6.2.5+). Review endpoint configurations.Check Version:
asadmin versionVerify Fix Applied:
Verify GlassFish version is updated beyond vulnerable range and test SSRF attempts against known vulnerable endpoints.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from GlassFish server
- Requests to internal IP ranges from GlassFish
- Error responses from internal services
Network Indicators:
- GlassFish server making unexpected HTTP requests
- Traffic to internal services from application server
SIEM Query:
source="glassfish" AND (http_request OR url_contains) AND (dest_ip=private_range OR dest_ip=loopback)
