Successful exploitation of this vulnerability could allow an attacker to adjust the Beacon configuration settings and/or disable the Bluetooth functionality of doors where non-networked Beacons are deployed.
The following Chirp Systems products are affected when deployed in non-networked beacon configurations:
The Chirp Access app contains a hard-coded password, BEACON_PASSWORD. An attacker within Bluetooth range could change configuration settings within the Bluetooth beacon, effectively disabling the application’s ability to notify users when they are near a Beacon-enabled access point. This variable cannot be used to change the configuration settings of the door readers or locksets and does not affect the ability for authorized users of the mobile application to lock or unlock access points.
CVE-2024-2197 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).
A CVSS v4 score has also been calculated for CVE-2024-2197. A base score of 2.3 has been calculated; the CVSS vector string is (CVSS4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N).
