CVE-2025-4530
📋 TL;DR
This CVE describes a path traversal vulnerability in the feng_ha_ha/megagao ssm-erp and production_ssm software versions 1.0. Attackers can exploit the handleFileDownload function in FileController.java to access arbitrary files on the server. Organizations using these ERP systems are affected.
💻 Affected Systems
- feng_ha_ha/megagao ssm-erp
- production_ssm
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through sensitive file disclosure (configuration files, credentials, database contents)
Likely Case
Unauthorized access to application files, configuration data, and potentially sensitive business information
If Mitigated
Limited file access restricted by proper input validation and file system permissions
🎯 Exploit Status
Exploit has been publicly disclosed and path traversal vulnerabilities are commonly weaponized
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider workarounds or replacing the software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize file paths before processing
Implement path normalization and validation in FileController.java before handleFileDownload
Web Application Firewall Rule
allBlock path traversal patterns in HTTP requests
Add WAF rule to block requests containing '../', '..\', or similar traversal patterns
🧯 If You Can't Patch
- Isolate the application in a restricted network segment with minimal file system access
- Implement strict file system permissions and run application with least privilege user account
🔍 How to Verify
Check if Vulnerable:
Check if running ssm-erp or production_ssm version 1.0 and examine FileController.java for path traversal vulnerabilitiesCheck Version:
Check application version in configuration files or deployment manifestsVerify Fix Applied:
Test file download functionality with traversal payloads (e.g., '../../etc/passwd') to ensure proper validation📡 Detection & Monitoring
Log Indicators:
- Multiple failed file access attempts with traversal patterns
- Unusual file access patterns from single IP
Network Indicators:
- HTTP requests containing '../' or similar traversal sequences
- Unusual file download patterns
