An issue was discovered on TENGCONTROL T-920 PLC v5.5 devices. It allows remote attackers to cause a denial of service (persistent failure mode) by sending a series of \x19\xb2\x00\x00\x00\x06\x43\x01\x00\xac\xff\x00 (aka UID 0x43) requests to TCP port 502.
Add your gear to cvedb and we'll alert you only when tengcon ships something exploited.
