Bug allows Hackers to open locked Biometric Fingerprint Doors

Researcher has uncovered various flaws in a Taiwan-based Chiyu Technology’s fingerprint access controller which could allow hackers to easily open the locked doors.

The researcher, Maxim Rupp has said that the vulnerabilities allow the attacker to view and modify the existing configuration of the device without authentication by directly accessing known paths. 

The path (CVE-2015-2871) varies slightly depending on model and services available.
According to an advisory published on July 31, the paths for accessing communications, fingerprint and other setup pages vary depending on the model and the services that are available, CERT/CC.
“It has identified models BF-660C, BF-630, BF-630W as being vulnerable; other models may also be vulnerable. The CERT/CC has been unable to verify this information with the vendor. The CVSS score below is based on CVE-2015-2871,” the advisory read.

According to a story published in SecurityWeek, the researcher said that by gaining access to the controller’s fingerprint setup page, an attacker could modify settings, such as “security level” and “sensitivity,” to make it easier to open the door protected by the device. An attacker can also change the device’s network settings and disconnect it from the targeted organization’s network.
“The researcher has also found that some of the vulnerable biometric devices are accessible via the Internet, which allows an attacker to exploit the weakness remotely. An attacker might be able to carry out other actions as well once he gains access to the controller’s configuration pages, but the expert says he hasn’t conducted further tests,” the report read.

The researcher said that there were several other companies that which sold the same devices under a different brand.

The flaws were reported by the researcher to Chiyu Technology via CERT/CC on May 29. CERT/CC. However, the company concerned has not managed to get in touch with the manufacturer.
It is still unclear that when the company will fix the flaws in the fingerprint access controller.
