VAR-202407-2539

Vulnerability from variot - Updated: 2025-11-18 12:06

An issue was discovered in Lush 2 through 2020-02-25. Due to the lack of Bluetooth traffic encryption, it is possible to hijack an ongoing Bluetooth connection between the Lush 2 and a mobile phone. This allows an attacker to gain full control over the device. This attack hijacks the connection, even when someone else was actively using the device before. Note that the user of the device remains capable of simply shutting it down. In order to exploit this vulnerability, the attacker must be present in a certain radius in which the Bluetooth connection can be intercepted. This attack vector also requires specific hardware like the Micro:bit.
