CVE-2024-44677
📋 TL;DR
CVE-2024-44677 is a critical Server-Side Request Forgery (SSRF) vulnerability in eladmin v2.7 and earlier that allows authenticated attackers to make arbitrary HTTP requests from the vulnerable server, potentially leading to remote code execution. This affects all deployments of eladmin version 2.7 and below. Attackers can exploit this to access internal systems, exfiltrate data, or execute commands on the server.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining remote code execution, accessing internal networks, and potentially pivoting to other systems.
Likely Case
Data exfiltration, internal network reconnaissance, and potential access to cloud metadata services leading to further compromise.
If Mitigated
Limited impact with proper network segmentation and egress filtering preventing access to internal resources.
🎯 Exploit Status
Exploit requires authenticated access. Public proof-of-concept code exists in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v2.8 or later
Vendor Advisory: https://github.com/elunez/eladmin
Restart Required: Yes
Instructions:
1. Backup current installation. 2. Update to eladmin v2.8 or later from official GitHub repository. 3. Restart the application server. 4. Verify the fix by checking the version.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation and URL filtering for DatabaseController endpoints
Add URL validation logic to DatabaseController.java to reject non-whitelisted URLs
Network Egress Filtering
linuxRestrict outbound network access from eladmin server
iptables -A OUTPUT -p tcp --dport 80 -j DROP
iptables -A OUTPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate eladmin server from internal resources
- Deploy web application firewall (WAF) with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check if running eladmin version 2.7 or earlier. Review DatabaseController.java for SSRF vulnerability patterns.Check Version:
Check application.properties or pom.xml for version informationVerify Fix Applied:
Verify version is 2.8 or later. Test SSRF payloads should be rejected.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from eladmin server
- Requests to internal IP addresses or cloud metadata endpoints
Network Indicators:
- HTTP traffic from eladmin server to unexpected destinations
- Requests to 169.254.169.254 (AWS metadata) or similar
SIEM Query:
