CVE-2025-3254
📋 TL;DR
This critical vulnerability in xujiangfei admintwo 1.0 allows remote attackers to perform server-side request forgery (SSRF) attacks by manipulating the description parameter in the /resource/add endpoint. Attackers can exploit this to make the server send unauthorized requests to internal systems. All users running the vulnerable version are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could pivot to internal networks, access sensitive internal services, perform data exfiltration, or use the server as a proxy for further attacks.
Likely Case
Unauthorized access to internal HTTP services, metadata services (like AWS/Azure instance metadata), or internal APIs leading to information disclosure.
If Mitigated
Limited impact with proper network segmentation, egress filtering, and input validation in place.
🎯 Exploit Status
Public exploit documentation exists on GitHub. The vulnerability requires minimal technical skill to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation to reject URLs in the description parameter
Modify /resource/add endpoint code to validate and sanitize description input
Web Application Firewall Rule
allBlock requests containing URLs in the description parameter
Add WAF rule: if request_uri contains '/resource/add' and parameter 'description' contains 'http://' or 'https://', then block
🧯 If You Can't Patch
- Implement network segmentation to restrict the server's outbound connections
- Deploy a reverse proxy with URL filtering for the /resource/add endpoint
🔍 How to Verify
Check if Vulnerable:
Test if submitting a URL in the description parameter of /resource/add causes the server to make external requestsCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that URL inputs in the description parameter are rejected or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from the server
- Multiple requests to /resource/add with URL-like parameters
Network Indicators:
- Server making unexpected HTTP requests to internal or external systems
