Chiyu Technology Fingerprint/RFID Access Controller

Multiple models of Chiyu Technology fingerprint access control devices contain an authentication bypass vulnerability and a cross-site scripting (XSS) vulnerability.

An unauthenticated remote attacker may be able to view or modify device configuration, or obtain user credentials.

CVE-2015-2871Authentication Bypass

According to the reporter, an attacker can view and modify the existing configuration of the device without authentication by directly accessing known paths. The path varies slightly depending on model and services available.

Model BF-660C:

http://<host>/net.htm – Communication settings

Model BF-630, BF-630W:

http://<host>/voice.htm – Voice Time Set
http://<host>/bf.htm – UniFinger Setup

The reporter has identified models BF-660C, BF-630, BF-630W as being vulnerable; other models may also be vulnerable.

CVE-2015-2870XSS

According to the reporter, <script> tags are not filtered out of a URL passed to the device, allowing an attacker to perform a reflected XSS attack.
