- The software that 3com has developed for running the NMC (network
- management card) for the Total Control Hubs is a bit shady.
- After uploading the software ( as one must do) YOU will notice a login
- account called "adm" with no password.
- Naturally no one wants the "adm" login there, so they delete it from the
- configuration, and go on programming the box. Once the box has been
- programmed and is ready to take calls, it is necessary to save all
- settings, and hardware reset the box, at this point the box is fully
- configured, and ready to
- take calls. The problem is this, the "adm" login requiring no password, is
- still there after the hardware reset!!! It cannot be deleted!
- I have ran a trace route on over 37 ISP's, found there HD box's, and
- have been able to get
- into 21 of them through this security hole!
- The admin that programmed the box has no reason to go back into the
- configuration after doing the
- hardware reset, he has already gone over and double checked his settings,
- they all looked good, and hardware reset has gone into action as the last
- step.., he has no clue that the "adm" he has deleted is still there, and
- active.
- In order to stop the "adm" login one can only dis-able the "adm"
- login, not delete it....this is the only way to stop the login.
-
- I have tested this on the current, and last 3 releases of software put out
- by 3com for the NMC card. 3Com has been notified
-
- I hope this helps.

- NMC card? The only card you can telnet to is the NAC (Network Access
- Card, I believe). The bug appears to be present on this card.

- Actually it's not the NMC card, its the HiPer ARC card.
-
- According to USR/3com personnel it is only affected in v4.1.x revisions
- of the HARC code.
-
- As posted, the fix is to disable the account.
