CVE-2023-1725
📋 TL;DR
This Server-Side Request Forgery (SSRF) vulnerability in Infoline Project Management System allows attackers to make unauthorized requests from the server to internal or external systems. It affects all versions before 4.09.31.125, potentially exposing internal network resources and enabling data exfiltration.
💻 Affected Systems
- Infoline Project Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of internal network resources, data exfiltration, and potential lateral movement to other systems through the vulnerable server.
Likely Case
Unauthorized access to internal services, metadata harvesting, and potential data leakage from internal APIs or services.
If Mitigated
Limited to port scanning internal networks or accessing publicly available external resources.
🎯 Exploit Status
SSRF vulnerabilities typically have low exploitation complexity and may not require authentication depending on the specific implementation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.09.31.125
Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-23-0187
Restart Required: Yes
Instructions:

🔧 Temporary Workarounds
Network Segmentation
allRestrict outbound network access from the vulnerable server to only necessary services
Input Validation
allImplement strict URL validation and whitelist allowed domains for server-side requests
🧯 If You Can't Patch
- Implement strict network egress filtering to limit the server's outbound connections
- Deploy a web application firewall (WAF) with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check the application version in the admin interface or configuration files. If version is below 4.09.31.125, the system is vulnerable.Check Version:
Check application admin panel or configuration files for version informationVerify Fix Applied:
Confirm the application version is 4.09.31.125 or higher after patching.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from the server
- Requests to internal IP addresses or localhost
- Multiple failed connection attempts to various ports
Network Indicators:
- Unexpected outbound traffic from the server to internal networks
- Port scanning patterns originating from the server
