CVE-2025-25760
📋 TL;DR
This SSRF vulnerability in SUCMS v1.0 allows attackers to make the server send requests to internal systems by manipulating the admin_webgather.php component. Attackers can potentially access sensitive internal data and services that should not be exposed. All SUCMS v1.0 installations with the vulnerable component are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could access internal databases, cloud metadata services, or administrative interfaces, potentially leading to full system compromise and data exfiltration.
Likely Case
Attackers scan internal networks, access internal APIs, or retrieve sensitive configuration data from cloud metadata services.
If Mitigated
With proper network segmentation and egress filtering, impact is limited to the web server itself with minimal data exposure.
🎯 Exploit Status
Requires crafting specific GET requests to the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - check vendor for updates
Vendor Advisory: Unknown
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. Apply any available patches. 3. Remove or restrict access to admin_webgather.php if not needed.
🔧 Temporary Workarounds
Restrict access to vulnerable component
allBlock access to admin_webgather.php via web server configuration or firewall rules.
# Apache: <Location /admin_webgather.php> Require all denied </Location>
# Nginx: location /admin_webgather.php { deny all; }
🧯 If You Can't Patch
- Implement strict egress filtering to limit outbound connections from the web server
- Deploy web application firewall with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Test if admin_webgather.php accepts URL parameters and makes external requests. Use controlled test to see if server makes requests to internal addresses.Check Version:
Check SUCMS version in admin panel or configuration files.Verify Fix Applied:
Attempt to trigger SSRF with test payloads and verify server does not make unauthorized requests.📡 Detection & Monitoring
Log Indicators:
- Unusual requests to admin_webgather.php with URL parameters
- Outbound connections from web server to internal IP ranges
Network Indicators:
- Web server making unexpected outbound HTTP requests
- Requests to internal services from web server IP
SIEM Query:
source="web_logs" AND uri="/admin_webgather.php" AND (query CONTAINS "url=" OR query CONTAINS "http")
