Attack Chain

1. The attacker identifies an Open ISES Tickets instance using InstaMapper or Google Latitude integration.
2. The attacker gains control over, or impersonates, the remote GPS tracker endpoint.
3. The attacker crafts malicious XML/JSON responses containing SQL injection payloads in the latitude, longitude, callsign, mph, altitude, or timestamp fields.
4. The Open ISES Tickets server parses the crafted XML/JSON response from the compromised GPS tracker.
5. The server concatenates the unsanitized data into UPDATE or INSERT SQL statements within incs/remotes.inc.php.
6. The injected SQL code is executed against the Open ISES Tickets database.
7. The attacker manipulates responder location, tracks, and assignment data within the database.
8. The attacker achieves their objective, such as diverting responders or falsifying tracking information.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-48235) could allow an attacker to manipulate responder deployments, tracks, and assignments. This could lead to incorrect responder dispatches, delayed response times, or complete disruption of the incident management system. The impact is significant, potentially affecting public safety and emergency response operations that rely on accurate location data.

Recommendation

• Upgrade Open ISES Tickets to version 3.44.2 or later to patch CVE-2026-48235.
• Implement input validation and sanitization on all GPS data received from external sources to prevent SQL injection, focusing on the latitude, longitude, callsign, mph, altitude, and timestamp fields.
• Deploy the Sigma rule Detect Suspicious GPS Data in Web Requests to identify potential SQL injection attempts.
• Harden the GPS tracker endpoint by implementing strong authentication and authorization controls to prevent unauthorized access and impersonation.
