CVE-2026-1022
📋 TL;DR
The Gotac Statistics Database System contains an arbitrary file read vulnerability that allows unauthenticated remote attackers to download any system file through relative path traversal. This affects all organizations using the vulnerable Gotac Statistics Database System software. Attackers can exploit this without authentication to access sensitive files.
💻 Affected Systems
- Gotac Statistics Database System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through reading sensitive files like /etc/passwd, /etc/shadow, configuration files with credentials, SSH keys, database files, and application source code, potentially leading to lateral movement and data exfiltration.
Likely Case
Unauthenticated attackers reading sensitive configuration files, user data, and system information that could be used for further attacks or data theft.
If Mitigated
Limited impact if system is behind strict network controls, file permissions are properly configured, and sensitive files are encrypted or stored outside accessible directories.
🎯 Exploit Status
Exploitation requires only HTTP requests with crafted path traversal sequences (e.g., ../../../etc/passwd). No authentication or special privileges needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check with Gotac vendor for specific patched version
Vendor Advisory: https://www.twcert.org.tw/en/cp-139-10640-0fd0b-2.html
Restart Required: Yes
Instructions:
1. Contact Gotac vendor for security patch
2. Apply the patch to all affected systems
3. Restart the Statistics Database System service
4. Verify the fix is working
🔧 Temporary Workarounds
Network Access Control
linuxRestrict network access to the Statistics Database System to only trusted IP addresses
iptables -A INPUT -p tcp --dport [PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [PORT] -j DROP
Web Application Firewall
allDeploy WAF rules to block path traversal patterns
🧯 If You Can't Patch
- Isolate the system in a separate network segment with strict access controls
- Implement file system monitoring and integrity checking for sensitive files
🔍 How to Verify
Check if Vulnerable:
Test by attempting to access system files via the vulnerable endpoint with path traversal sequences (e.g., GET /download?file=../../../etc/passwd)Check Version:
Check application version through web interface or configuration filesVerify Fix Applied:
Attempt the same path traversal attack after patching - it should return an error or sanitized response📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing ../ sequences
- Access to unusual file paths in download logs
- Multiple failed file access attempts
Network Indicators:
- Unusual patterns of file download requests
- Requests for known system file paths
