CVE-2017-5623: Oneplus Oxygenos

Medium severity, CVSS 6.6. EPSS: 0.4% chance of exploitation in the next 30 days.

An issue was discovered in OxygenOS before 4.1.0 on OnePlus 3 and 3T devices. The attacker can change the bootmode of the device by issuing the 'fastboot oem boot_mode {rf/wlan/ftm/normal} command' in contradiction to the threat model of Android where the bootloader MUST NOT allow any security-sensitive operation to be run unless the bootloader is unlocked.

Affected products

• Oneplus Oxygenos: up to and including 4.0.3
