CVE-2025-54819
📋 TL;DR
A path traversal vulnerability in SS1 Ver.16.0.0.10 and earlier allows remote authenticated attackers to overwrite legitimate files by manipulating file paths. This affects users of SS1 software versions up to 16.0.0.10 and Media versions up to 16.0.0a.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Critical system files could be overwritten, leading to system compromise, data loss, or service disruption.
Likely Case
Attackers overwrite configuration files or upload malicious content to gain persistence or disrupt operations.
If Mitigated
With proper access controls and monitoring, impact is limited to unauthorized file modifications within the application's scope.
🎯 Exploit Status
Path traversal vulnerabilities typically have low exploitation complexity once authentication is bypassed or obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after SS1 Ver.16.0.0.10 and Media version after 16.0.0a
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. 3. Install the update following vendor instructions. 4. Restart the application/service.
🔧 Temporary Workarounds
Restrict file upload paths
allConfigure the application to only allow file operations within specific safe directories.
Implement input validation
allAdd server-side validation to reject path traversal sequences like '../' in file operations.
🧯 If You Can't Patch
- Implement strict access controls and limit authenticated user privileges
- Monitor file system changes and audit logs for suspicious file operations
🔍 How to Verify
Check if Vulnerable:
Check SS1 version in administration interface or configuration files. If version is 16.0.0.10 or earlier, you are vulnerable.Check Version:
Check application documentation for version command, typically in admin interface or configuration files.Verify Fix Applied:
Verify the version is updated to later than 16.0.0.10 and test file upload functionality with traversal attempts.📡 Detection & Monitoring
Log Indicators:
- Unusual file write operations
