Guardian AST Automatic Tank Gauge Detection Scanner

Guardian AST Automatic Tank Gauge systems are widely used in fuel storage facilities for inventory management and environmental monitoring. They are typically employed by fuel stations, industrial facilities, and logistics companies to monitor and report fuel levels and other tank conditions. These systems help streamline fuel inventory management, reduce manual errors, and ensure compliance with environmental regulations. The system communicates with remote servers or management systems to provide real-time data.

This scanner identifies the presence of Guardian AST Automatic Tank Gauge systems by querying their standard I20100 command. It verifies the system's response, which contains tank inventory details, and validates whether the response matches the expected protocol structure. The scanner operates non-intrusively, ensuring no disruption to the functionality of the targeted system during detection. This is an informational scan intended to identify systems for inventory purposes without exploitation.

The scanner sends a TCP query to port 10001, commonly used by Guardian AST devices, and parses the response. If the system is recognized as Guardian AST, the scanner provides information about the tank inventory and other device attributes. It leverages a well-defined communication protocol to ascertain device presence accurately.

If the vulnerability is exploited, attackers could potentially gain access to sensitive inventory data. Such information could be leveraged to disrupt operations, manipulate inventory records, or plan unauthorized physical access to fuel storage systems. While this scan is informational, such systems should be adequately secured to prevent unauthorized access.
