🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions newer than SS1 Ver.16.0.0.10 and Media version:16.0.0a
Vendor Advisory: https://www.dos-osaka.co.jp/news/2025/08/250827.html
Restart Required: Yes
Instructions:
1. Check current SS1 version. 2. Download and install the latest version from the vendor. 3. Restart the SS1 service or system as required.
🔧 Temporary Workarounds
Restrict network access
allLimit network access to SS1 systems to trusted IP addresses only.
Use firewall rules to restrict access (e.g., iptables -A INPUT -p tcp --dport [SS1_PORT] -s [TRUSTED_IP] -j ACCEPT)
Implement web application firewall
allDeploy a WAF to block unauthorized file access attempts.
Configure WAF rules to detect and block patterns like '../' or file enumeration attempts
🧯 If You Can't Patch
- Isolate SS1 systems on a segmented network with strict access controls.
- Implement monitoring and alerting for unauthorized file access attempts.
🔍 How to Verify
Check if Vulnerable:
Check the SS1 version in the system settings or configuration files against the affected version range.Check Version:
Check SS1 documentation for version command, typically in admin interface or configuration files.Verify Fix Applied:
Confirm the SS1 version is newer than the affected versions and test file access controls.📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns, especially from unauthenticated or external IPs
- Failed or successful access to configuration or uploaded files
Network Indicators:
- HTTP requests attempting to access known configuration file paths or uploaded directories
