9.8 · CRITICALOverview
CVE-2019-13143 is a critical-severity vulnerability affecting shenzhen_dragon_brothers fb50_firmware. It was published on August 6, 2019 and has a CVSS 3.0 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.0 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
An HTTP parameter pollution issue was discovered on Shenzhen Dragon Brothers Fingerprint Bluetooth Round Padlock FB50 2.3. With the user ID, user name, and the lock's MAC address, anyone can unbind the existing owner of the lock, and bind themselves instead. This leads to complete takeover of the lock. The user ID, name, and MAC address are trivially obtained from APIs found within the Android or iOS application. With only the MAC address of the lock, any attacker can transfer ownership of the lock from the current user, over to the attacker's account. Thus rendering the lock completely inaccessible to the current user.
Remediation
Check the references section for vendor advisories and patches from shenzhen_dragon_brothers. Update fb50_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
