CVE-2025-24485
📋 TL;DR
An unauthenticated server-side request forgery vulnerability in MedDream PACS Premium allows attackers to make arbitrary HTTP requests from the vulnerable server. This could lead to internal network scanning, data exfiltration, or attacks against internal services. All systems running the affected version are vulnerable by default.
💻 Affected Systems
- MedDream PACS Premium
📦 What is this software?
Pacs Server by Meddream
⚠️ Risk & Real-World Impact
Worst Case
Attacker accesses internal services, exfiltrates sensitive data, or uses the server as a pivot point for further attacks on the internal network.
Likely Case
Internal network reconnaissance, limited data exposure from services accessible to the server, or denial of service against internal systems.
If Mitigated
Limited impact if network segmentation restricts server access to only necessary services and external requests are blocked.
🎯 Exploit Status
Exploitation requires sending a specially crafted HTTP request to the cecho.php endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor vendor for security updates. 2. Apply patch when available. 3. Test in non-production environment first.
🔧 Temporary Workarounds
Block cecho.php endpoint
allRestrict access to the vulnerable cecho.php file using web server configuration or firewall rules.
# Apache: RewriteRule ^/cecho\.php$ - [F,L]
# Nginx: location ~ /cecho\.php$ { deny all; }
Network segmentation
allRestrict outbound HTTP/HTTPS connections from the MedDream server to only necessary destinations.
🧯 If You Can't Patch
- Implement strict network segmentation to limit the server's access to internal resources
- Deploy a web application firewall with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check if cecho.php is accessible without authentication and responds to crafted requests with server-side HTTP calls.Check Version:
Check MedDream version in administration interface or configuration filesVerify Fix Applied:
Verify cecho.php endpoint is no longer accessible or properly validates input to prevent SSRF.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests to cecho.php with external URLs in parameters
- Outbound HTTP requests from server to unexpected internal/external destinations
Network Indicators:
- HTTP traffic from MedDream server to unusual internal IPs or external domains
