Kaspersky Lab researchers have helped uncover a number of unknown vulnerabilities that have left gas stations around the world exposed to remote takeover, often for years. The vulnerabilities were found in an embedded gas station controller of which there are currently over 1,000 installed and online. The manufacturer was notified when the threat was confirmed.
Ido Naor, senior security researcher at Kaspersky Lab, together with another researcher found the controller during unrelated research into devices with open connections to the internet. In many cases the controller had been placed in the fuel station over a decade ago and had been connected to the internet ever since.
The controller, which runs a Linux machine, operates with high privileges and the researchers discovered a number of vulnerabilities that leave the device and the systems it is connected to open to cyberattack. For example, the researchers were able to monitor and configure many of the gas station settings. An intruder able to bypass the login screen and gain access to the main interfaces would be able to do any of the following:
Shut down all fueling systems
Change the fuel prices
Cause fuel leakages
Circumvent payment terminals to steal money (the controller connects directly to the payment terminal, so payment transactions could be hijacked)
Scrape vehicle license plates and driver identities
Execute code on the controller unit
Move freely within the gas station network
“When it comes to connected devices it is easy to focus on the new and to forget about products installed many years ago that might be leaving the business wide open to attack. The damage that could be done by sabotaging a gas station doesn’t bear thinking about. We have shared our findings with the manufacturer,” said Ido Naor, Senior Security Researcher at Kaspersky Lab.
The vulnerabilities have been reported to MITRE and the research is ongoing.
Kaspersky Lab advises manufacturers of connected internet-of-thing devices to consider the security of their products from the very first moment of development and design, and to review legacy devices for possible security vulnerabilities. Users of connected devices are urged to review regularly the security of these devices and not to rely on factory settings.

MITRE is a non-profit organization which operates federally-funded research and development centers and maintains the Common Vulnerabilities and Exposures (CVE) system. MITRE has listed Kaspersky Lab as a CNE Numbering Authority (CNA) which means the cybersecurity company can assign CVE numbers to newly identified vulnerabilities and publicly disclose information on them.
