CVE-2025-3572
📋 TL;DR
SmartRobot from INTUMIT has an unauthenticated Server-Side Request Forgery vulnerability that allows attackers to make the server send requests to internal network resources and access local files. This affects all organizations using vulnerable versions of SmartRobot software. Attackers can exploit this without any authentication.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could access sensitive internal systems, steal credentials, read arbitrary files on the server, and pivot to other internal network resources.
Likely Case
Attackers will probe internal networks, access local files containing configuration data or credentials, and potentially use this as an initial foothold for further attacks.
If Mitigated
With proper network segmentation and access controls, impact would be limited to the isolated server environment only.
🎯 Exploit Status
SSRF vulnerabilities are typically easy to exploit with basic web testing tools. No authentication required makes this particularly dangerous.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in provided references
Vendor Advisory: https://www.twcert.org.tw/en/cp-139-10065-2494c-2.html
Restart Required: Yes
Instructions:
1. Check vendor advisory for specific patch version. 2. Download and apply the patch from INTUMIT. 3. Restart SmartRobot services. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Network Segmentation
allRestrict outbound network access from SmartRobot server to only necessary destinations
Web Application Firewall
allDeploy WAF rules to block SSRF patterns and URL-based attacks
🧯 If You Can't Patch
- Isolate SmartRobot server in a restricted network segment with no access to internal resources
- Implement strict egress filtering to prevent the server from making requests to internal IP ranges
🔍 How to Verify
Check if Vulnerable:
Test if the SmartRobot interface accepts URLs pointing to internal resources (like http://localhost, http://127.0.0.1, or internal IP addresses) and returns their content.Check Version:
Check SmartRobot administration interface or configuration files for version informationVerify Fix Applied:
After patching, repeat the vulnerability test to confirm internal resources can no longer be accessed.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound requests from SmartRobot server to internal IP addresses
- Requests containing localhost, 127.0.0.1, or file:// protocols in URL parameters
Network Indicators:
- SmartRobot server making unexpected connections to internal services
- Outbound requests to non-standard ports from SmartRobot
