CVE-2021-20592

Missing synchronization vulnerability in GOT2000 series GT27 model communication driver versions 01.19.000 through 01.39.010, GT25 model communication driver versions 01.19.000 through 01.39.010 and GT23 model communication driver versions 01.19.000 through 01.39.010 and GT SoftGOT2000 versions 1.170C through 1.256S allows a remote unauthenticated attacker to cause DoS condition on the MODBUS/TCP slave communication function of the products by rapidly and repeatedly connecting and disconnecting to and from the MODBUS/TCP communication port on a target. Restart or reset is required to recover.
