CVE-2026-1330
📋 TL;DR
MeetingHub software from HAMASTAR Technology contains an absolute path traversal vulnerability that allows unauthenticated remote attackers to read arbitrary files on the system. This affects all organizations using vulnerable versions of MeetingHub, potentially exposing sensitive system files and configuration data.
💻 Affected Systems
- MeetingHub
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could download critical system files like /etc/passwd, /etc/shadow, configuration files, database credentials, or sensitive application data, leading to complete system compromise.
Likely Case
Attackers will exfiltrate sensitive configuration files, user data, and system information that can be used for further attacks or data theft.
If Mitigated
With proper network segmentation and access controls, impact is limited to the application server's file system, though sensitive data may still be exposed.
🎯 Exploit Status
The vulnerability is simple to exploit using path traversal sequences like '../../' in file download requests.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2026.1.1
Vendor Advisory: https://www.twcert.org.tw/en/cp-139-10651-ff09c-2.html

🔧 Temporary Workarounds
Network Access Restriction
allRestrict access to MeetingHub to trusted IP addresses only
Web Application Firewall Rules
allBlock path traversal patterns in HTTP requests
🧯 If You Can't Patch
- Isolate MeetingHub server in a restricted network segment
- Implement strict file system permissions and disable unnecessary file access
🔍 How to Verify
Check if Vulnerable:
Attempt to access a system file using path traversal in MeetingHub's file download endpoint (e.g., request '../../../../etc/passwd')Check Version:
Check MeetingHub admin interface or application logs for version informationVerify Fix Applied:
After patching, attempt the same path traversal attack - it should return an error or be blocked📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '../' sequences
- Unusual file access patterns from external IPs
- Failed authentication attempts followed by file download requests
Network Indicators:
- Multiple requests for system files from single IP
- Patterns of '../../' in URL parameters
- Unusual outbound data transfers
