CVE-2026-1332
📋 TL;DR
MeetingHub software from HAMASTAR Technology has a missing authentication vulnerability that allows unauthenticated remote attackers to access specific API functions. This enables unauthorized viewing of meeting-related information. Organizations using vulnerable versions of MeetingHub are affected.
💻 Affected Systems
- MeetingHub
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could access sensitive meeting details, participant information, and potentially meeting recordings or documents, leading to data breach and privacy violations.
Likely Case
Unauthorized access to meeting metadata, participant lists, and basic meeting information, potentially enabling reconnaissance for further attacks.
If Mitigated
Limited exposure with proper network segmentation and access controls, but still vulnerable to internal threats.
🎯 Exploit Status
Exploitation requires identifying vulnerable API endpoints but does not require authentication bypass techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in references; check vendor advisory
Vendor Advisory: https://www.twcert.org.tw/en/cp-139-10651-ff09c-2.html
Restart Required: Yes
Instructions:
1. Check vendor advisory for specific patched version. 2. Backup current configuration. 3. Apply vendor-provided patch or update to fixed version. 4. Restart MeetingHub services. 5. Verify authentication is required for all API endpoints.
🔧 Temporary Workarounds
Network Access Control
linuxRestrict network access to MeetingHub API endpoints using firewall rules
iptables -A INPUT -p tcp --dport [MEETINGHUB_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [MEETINGHUB_PORT] -j DROP
Reverse Proxy Authentication
allPlace MeetingHub behind a reverse proxy that requires authentication
# Configure nginx/apache with authentication before proxying to MeetingHub
🧯 If You Can't Patch
- Implement network segmentation to isolate MeetingHub from untrusted networks
- Deploy web application firewall (WAF) with authentication requirement rules for API endpoints
🔍 How to Verify
Check if Vulnerable:
Attempt to access MeetingHub API endpoints without authentication using curl: curl -X GET http://[meetinghub_host]/api/[endpoint]Check Version:
Check MeetingHub admin interface or configuration files for version informationVerify Fix Applied:
Test API endpoints require authentication after patch: curl -X GET http://[meetinghub_host]/api/[endpoint] should return 401/403📡 Detection & Monitoring
Log Indicators:
- Unauthenticated API access attempts
- Multiple failed authentication attempts followed by successful API calls
- Access to meeting-related API endpoints from unexpected IPs
Network Indicators:
- Unencrypted API calls to meeting endpoints
- Traffic patterns showing API access without authentication headers
SIEM Query:
source="meetinghub" AND (http_status=200 OR http_status=201) AND NOT (auth_token EXISTS OR session_id EXISTS)
