Vulnerabilities in Android-based PoS Terminals: A Deep Dive into PAX Technology’s Security Concerns

In the constantly evolving landscape of payment processing, Point of Sale (PoS) terminals play a crucial role. However, PAX Technology, a prominent provider of Android-based PoS terminals, faces critical vulnerabilities that can be exploited by malicious actors. In this article, we will explore the series of vulnerabilities affecting PAX terminals, their potential impact, and the necessary mitigation strategies.

Vulnerabilities in PAX PoS Terminals

The first vulnerability discovered affects PAX A920 devices, enabling attackers to downgrade the bootloader to a previous, potentially vulnerable version. This attack vector could pave the way for unauthorized access to the terminal’s functionality.

In the second vulnerability, attackers can inject kernel arguments, granting them the ability to execute arbitrary code with root privileges on any PAX PoS device. Although sandboxing prevents application interference, an attacker with root access could tamper with any application, including the payment process.

PAX A920Pro/A50 devices are vulnerable to code execution by flashing a different unsigned partition. This vulnerability poses additional risks as attackers can potentially execute malicious code, jeopardizing the integrity of the terminal’s operations.

Three critical vulnerabilities have been identified that require physical USB access. Attackers gaining physical access to a vulnerable PoS terminal could exploit these vulnerabilities, enabling various types of attacks with severe consequences.

Shell Access Vulnerabilities

Two vulnerabilities have been discovered that can be exploited by attackers with shell access. This means that unauthorized individuals can execute arbitrary commands on a vulnerable PoS device, opening the door to potential unauthorized modifications and breaches.

While these vulnerabilities raise serious concerns, it’s important to note that full exploitation requires root access or physical USB access. The presence of sandboxing mitigates the risk of application interaction. However, the potential impact remains significant, as attackers could modify transaction amounts and other related data. To address these vulnerabilities, businesses and users must prioritize security measures and implement best practices.

Upon being informed by STM Cyber and CERT Poland, PAX Technology promptly responded to the identified vulnerabilities. Recognizing the importance of responsible disclosure, they released comprehensive patches, aiming to address all the vulnerabilities. Timely patching and vigilant installation of updates are crucial in maintaining the security of PoS terminals.

Android-based PoS terminals from PAX Technology have been found to be susceptible to multiple vulnerabilities, which allow attackers to execute arbitrary code or commands. The potential risks posed by these vulnerabilities call for heightened security measures and adherence to industry best practices. Businesses and PoS terminal users must prioritize security updates, regularly patch vulnerabilities, and follow security guidelines to mitigate the risk of exploitation. By doing so, they can safeguard their operations and customers’ sensitive payment information from potential threats.
