CLI backdoor

It appears the backdoor I found earlier in the 3coms during bootup is also available on the CLI when logged in.

First you press <CTRL-G>, then you enter the password.

For the 3com firmware they are:

d3bug1191 – Enter 3Com SuperStack 3 Switch 3870 48-port debug backdoor

acct0ncl1 – Enter Accton CLI backdoor

For the Edgecore firmware there is:

mercury – Enter 44GE+4Combo Layer2/3/4 Stackable Switch debug backdoor

These backdoors are only available when connected through serial console and logged in. Not when logged in via telnet. “vdsl” also appears to be something, but not sure yet what this does or anything at all.
