The weird thing about this advisory is that the hardcoded IP addresses (202.114.4[.]119) are the same ones found in the online installation manuals for Contec and affiliated brands ( https://help.xchart.com/en/articles/7943824-configuring-edan... ).
This was confirmed through firmware analysis: https://x.com/craiu/status/1885341007576801338 and in the manuals: https://infosec.exchange/@decio/113928319441297901
