Cybersecurity researchers from BitSight TRACE have uncovered multiple 0-day vulnerabilities in Automated Tank Gauge (ATG) systems, which are integral to managing fuel storage tanks across various critical infrastructures.
These vulnerabilities in six ATG systems from five vendors pose significant threats to public safety and economic stability.
The flaws could potentially be exploited by malicious actors to cause physical damage, environmental hazards, and economic losses.
The Role of ATG Systems in Critical Infrastructure
Automatic Tank Gauging (ATG) systems are designed to automatically measure and record product level, volume, and temperature in storage tanks.
These systems are used in gas stations and are prevalent in military bases, hospitals, airports, emergency services, and power plants.
They are crucial in ensuring compliance with environmental regulations and optimizing inventory management. However, their exposure to the internet makes them vulnerable targets for cyberattacks.

Details of the Vulnerabilities
The investigation by BitSight TRACE identified 11 vulnerabilities across several ATG models. These include OS command injection, authentication bypasses, hardcoded credentials, and SQL injection vulnerabilities.
Each flaw allows attackers to gain full administrative control over the ATG systems.
The vulnerabilities have been assigned CVE identifiers with critical CVSS scores, highlighting their severity: here is a summary of the CVE table data related to the vulnerabilities found in Automated Tank Gauge (ATG) systems:
These security flaws reflect fundamental design issues that should have been addressed long ago.
The exploitation of these vulnerabilities could lead to severe consequences:
- Denial of Service (DoS): Attackers could disable ATG systems by reconfiguring settings or flashing faulty firmware.
- Physical Damage: By altering critical parameters such as tank geometry and capacity, attackers could cause fuel leaks or disable alarms.
- Data Theft: Sensitive operational data could be captured and sold to third parties.
- Network Intrusion: Vulnerable ATG systems could serve as entry points for further attacks on internal networks.
These scenarios underscore the urgent need for enhanced security measures to protect these systems from exploitation.
Coordinated Efforts for Mitigation
BitSight has been working closely with the U.S. Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) to mitigate these vulnerabilities through responsible disclosure.
They have collaborated with affected vendors for six months to develop remediation strategies.
CISA has published advisories to guide organizations in securing their ATG systems against potential attacks.
The discovery of these vulnerabilities highlights the critical need for improved cybersecurity practices in industrial control systems like ATGs.
These systems are integral to national infrastructure, so their security must be prioritized to prevent potential disasters. Organizations are urged to disconnect ATGs from the internet and implement robust security measures to safeguard against future threats.
