Vulnerability from variot

A denial of service condition exists after an integer overflow in several IoT devices from CHIYU Technology, including BIOSENSE, Webpass, and BF-630, BF-631, and SEMAC. The vulnerability can be explored by sending an unexpected integer (> 32 bits) on the page parameter that will crash the web portal and making it unavailable until a reboot of the device. Chiyu CHIYU BF-430 is a network server provided by Chiyu Technology (Chiyu) of Taiwan, China, which provides communication for access control, time and attendance systems and other equipment. The following products and versions are affected: BIOSENSE, Webpass, and BF-630, BF-631, SEMAC
