CVE-2025-58072
📋 TL;DR
A path traversal vulnerability in SS1 Ver.16.0.0.10 and earlier allows remote unauthenticated attackers to view arbitrary files on the system. This affects all systems running vulnerable versions of SS1 software, potentially exposing sensitive data.
💻 Affected Systems
- SS1
⚠️ 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.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through reading sensitive files like configuration files, credentials, or system files that could lead to further attacks.
Likely Case
Unauthorized access to sensitive files containing application data, user information, or configuration details.
If Mitigated
Limited file access restricted by proper input validation and directory permissions.
🎯 Exploit Status
Path traversal vulnerabilities typically have low exploitation complexity, especially with unauthenticated access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Ver.16.0.0.11 or later
Vendor Advisory: https://www.dos-osaka.co.jp/news/2025/08/250827.html
Restart Required: Yes
Instructions:
1. Download the latest version from the vendor. 2. Backup current configuration and data. 3. Install the updated version. 4. Restart the SS1 service or system.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to SS1 services to trusted IP addresses only.
Use firewall rules to limit access: iptables -A INPUT -p tcp --dport [SS1_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [SS1_PORT] -j DROP
Application Firewall Rules
allImplement WAF rules to block path traversal patterns.
Add WAF rule to block requests containing '../', '..\', or similar traversal patterns
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable systems
- Deploy web application firewall with path traversal detection rules
🔍 How to Verify
Check if Vulnerable:
Check SS1 version in administration interface or configuration files. If version is 16.0.0.10 or earlier, the system is vulnerable.Check Version:
Check SS1 web interface or configuration files for version information. No universal command available.Verify Fix Applied:
Verify SS1 version is 16.0.0.11 or later after patching. Test file access attempts with traversal patterns to confirm they are blocked.📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '../', '..\', or similar traversal patterns
- Unusual file access patterns from external IPs
- Failed authentication attempts followed by file access attempts
Network Indicators:
- HTTP requests with encoded traversal sequences (%2e%2e%2f)
- Multiple file access attempts from single source
SIEM Query:
source="ss1_logs" AND (http_uri="*../*" OR http_uri="*..\\*" OR http_uri="*%2e%2e%2f*")
