Bug #16782
open
Trying to cancel ping (option 7) from console menu drops user into password change flow
Added by → luckman212 1 day ago.
Updated about 22 hours ago.
Affected Plus Version:
26.03
Description
This is a relatively minor issue, but it is strange/unexpected.
Choosing option '7' (Ping host) from the console menu, and then trying to cancel with ^c instead of providing a hostname to ping sends the user into a forced "Password MUST be changed" flow. Attempting to ^c again will terminate the entire SSH session.
Screenshot attached.

I can't reproduce this here. Is that on a fresh installation? Can you reproduce it every time you invoke the option? Was the password every actually changed to something other than the default?
That would normally only happen if the current menu was started before the password was changed on the first post-install boot. Once the password has been changed, that shouldn't be displayed.
No, this isn't a fresh installation.
Yes I can reproduce it every time.
I also just tested on another 2100 running 26.03 (which was very recently clean-installed) and was able to reproduce it there as well.
Yes in both cases, the password has definitely been changed from the default.
FYI- I can reproduce it from the serial console (in addition to via SSH)

To reproduce this you must hit ctl+c twice quite rapidly. So it appears to escape the menu before ctl+c is captured.

Spamming ^C is a bad practice in general, but unfortunately common. The script drawing the menu can capture its own signals, but not signals for child processes. If you press ^C multiple times rapidly it will kill other things running to render the menu and could have other impacts, but in this case it appears to be canceling the password check.
This change appears to catch that case and not fall into the password change for me:
