CVE-2024-11837
📋 TL;DR
This CVE describes an N1QL injection vulnerability in PlexTrac that allows attackers to execute arbitrary N1QL commands against the underlying database. This affects PlexTrac installations from version 1.61.3 through versions before 2.8.1. Attackers could potentially read, modify, or delete sensitive data in the database.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the PlexTrac database including exfiltration of all pentest reports, client data, credentials, and potential remote code execution on the database server.
Likely Case
Unauthorized access to sensitive pentest data, client information, and potential data manipulation or deletion.
If Mitigated
Limited data exposure if proper network segmentation and database permissions are configured, but injection still possible.
🎯 Exploit Status
N1QL injection typically requires some level of access to the application interface, but once accessed, exploitation is straightforward for attackers familiar with NoSQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.8.1 and later
Vendor Advisory: https://docs.plextrac.com/plextrac-documentation/master/security-advisories#release-2.11.0
Restart Required: Yes
Instructions:
1. Backup your PlexTrac data and configuration. 2. Upgrade to PlexTrac version 2.8.1 or later. 3. Restart the PlexTrac service. 4. Verify the upgrade was successful.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional input validation and sanitization for all user inputs that interact with N1QL queries.
Network Segmentation
allRestrict network access to PlexTrac instances to only authorized users and systems.
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries at the application layer
- Deploy a web application firewall (WAF) with NoSQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Check PlexTrac version via admin interface or configuration files. If version is between 1.61.3 and less than 2.8.1, the system is vulnerable.Check Version:
Check PlexTrac admin dashboard or configuration files for version informationVerify Fix Applied:
Verify PlexTrac version is 2.8.1 or higher and test N1QL query interfaces for proper input validation.📡 Detection & Monitoring
Log Indicators:
- Unusual N1QL query patterns
- Multiple failed query attempts with special characters
- Database error logs showing malformed queries
Network Indicators:
- Unusual database query traffic patterns
- Requests containing N1QL injection payloads
