Potential vulnerability in NVR
Hi, thanks for your response, I did manage to get the file 'DH_NVR5XXX-4KS2_MultiLang_V4.002.0000000.8.R.241030.zip' from vendor portal and upgraded my NVR, however remote login attempt still persisted, it looks like the vulnerability has not been fixed in latest FW release.- funtoosko
