CVE-2017-17910 is a medium-severity flaw (CVSS 6.5) affecting hs5-868-bs firmware, hse2-868-bs firmware, hse1-868-bs firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
On Hoermann BiSecur devices before 2018, a vulnerability can be exploited by recording a single radio transmission. An attacker can intercept an arbitrary radio frame exchanged between a BiSecur transmitter and a receiver to obtain the encrypted packet and the 32-bit serial number. The interception of the one-time pairing process is specifically not required. Due to use of AES-128 with an initial static random value and static data vector (all of
