Description

The researchers discovered three vulnerabilities in Lamassu Douro bitcoin ATMs could potentially allow attackers with physical access to take control of devices and pilfer user assets, according to cybersecurity firm IOActive. The vulnerabilities tracked as CVE-2024-0175, CVE-2024-0176, and CVE-2024-0177, these security flaws could be exploited with the same level of physical access as a regular customer. During the boot process, the Douro ATM allowed users to interact with the underlying operating system's window manager for a brief period. IOActive found that this short timeframe was sufficient for an attacker to run applications or open a terminal window, exploiting a vulnerability in the ATM's software update mechanism. The researchers also discovered a weak root password shared across all devices, crackable within a minute. Leveraging the ATM's support for reading QR codes, the team crafted a malicious code containing their payload, leading to a root shell. IOActive noted that attackers, gaining control of the ATM, could potentially manipulate and steal from users' accounts or wallets. Lamassu was informed of these issues in July 2023 and addressed them in October by implementing stronger security measures in the update process.
