CVE-2024-4538
📋 TL;DR
An Insecure Direct Object Reference (IDOR) vulnerability in Janto Ticketing Software version 4.3r10 allows remote attackers to access other users' event tickets by manipulating ticket reference IDs in requests. This exposes sensitive user data including ticket details and potentially personal information. Organizations using Janto Ticketing Software 4.3r10 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Mass data breach where attackers systematically harvest all user ticket data, leading to privacy violations, identity theft, and regulatory penalties.
Likely Case
Targeted data theft where attackers access specific users' ticket information for fraud, harassment, or competitive intelligence.
If Mitigated
Limited exposure with proper access controls and monitoring catching unauthorized access attempts early.
🎯 Exploit Status
Exploitation requires valid user credentials but minimal technical skill - attackers simply need to manipulate ticket IDs in requests.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 4.3r10 (check vendor advisory)
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-janto-ticketing-software
Restart Required: Yes
Instructions:
1. Backup current installation and data. 2. Download latest patched version from vendor. 3. Follow vendor upgrade instructions. 4. Restart application services. 5. Verify fix by testing IDOR attempts.
🔧 Temporary Workarounds
Implement Access Control Middleware
allAdd server-side validation to verify users can only access their own ticket data
Implement authorization check before ticket data retrieval: if (current_user.id != ticket_owner.id) { deny_access(); }
Use Obfuscated IDs
allReplace sequential ticket IDs with UUIDs or encrypted tokens
Replace ticket_id parameter with encrypted token: ticket_token = encrypt(ticket_id + user_id + salt)
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to detect and block IDOR patterns in requests
- Enable detailed logging of all ticket access attempts and implement real-time alerting for suspicious patterns
🔍 How to Verify
Check if Vulnerable:
1. Log in as user A. 2. Note user A's ticket ID. 3. Log in as user B. 4. Attempt to access user A's ticket using the noted ID. If successful, system is vulnerable.Check Version:
Check software version in admin panel or configuration files (typically version.txt or similar)Verify Fix Applied:
Repeat the vulnerability check steps - accessing another user's ticket should return access denied error.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authorization attempts for ticket access
- User accessing tickets with IDs outside their normal range
- Rapid sequential access to different ticket IDs
Network Indicators:
- HTTP requests with manipulated ticket_id parameters
- Unusual patterns in ticket API calls
SIEM Query:
source="web_logs" AND (ticket_access AND user_id != ticket_owner_id) OR (rapid_ticket_id_enumeration)
