CVE-2026-1020
📋 TL;DR
The Police Statistics Database System developed by Gotac contains an absolute path traversal vulnerability that allows unauthenticated remote attackers to enumerate system file directories. This affects organizations using this specific database system, potentially exposing sensitive file structures and metadata.
💻 Affected Systems
- Police Statistics Database System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could map the entire filesystem, identify sensitive configuration files, credentials, or backup locations, leading to further exploitation or data exfiltration.
Likely Case
Attackers will enumerate directory structures to identify valuable targets for subsequent attacks, potentially discovering other vulnerabilities or misconfigurations.
If Mitigated
With proper network segmentation and access controls, impact is limited to directory enumeration without access to sensitive data.
🎯 Exploit Status
Absolute path traversal vulnerabilities typically require minimal technical skill to exploit for directory enumeration
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in references; contact vendor for patched version
Vendor Advisory: https://www.twcert.org.tw/en/cp-139-10638-0e44b-2.html
Restart Required: Yes
Instructions:
1. Contact Gotac vendor for security patches
2. Apply vendor-provided patches to affected systems
3. Restart the Police Statistics Database System service
4. Verify the fix prevents directory traversal
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to the database system to only trusted IP addresses
Use firewall rules to limit access: iptables -A INPUT -p tcp --dport [PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [PORT] -j DROP
Web Application Firewall
allImplement WAF rules to block path traversal patterns
Configure WAF to block requests containing '../', '..\', or absolute path patterns
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the database system from untrusted networks
- Deploy intrusion detection systems to monitor for directory traversal attempts and alert on suspicious activity
🔍 How to Verify
Check if Vulnerable:
Test if the system responds to path traversal attempts (e.g., requests containing '../' or absolute paths) with directory listingsCheck Version:
Check system documentation or contact vendor for version identification methodsVerify Fix Applied:
Attempt the same path traversal tests after patching; successful fix should return error messages or deny access instead of directory listings📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '../', '..\', or absolute file paths
- Unusual access patterns to system directories
- Multiple failed attempts to access restricted paths
Network Indicators:
- Unusual traffic patterns to database system ports
- Requests with path traversal patterns in URI
SIEM Query:
source="web_logs" AND (uri="*../*" OR uri="*..\\*" OR uri="/etc/*" OR uri="/windows/*")
