I think, there is another workaround. You can reverse order of
characters in lines, cut fields from 7th to the end, then reverse lines
one more time.
E.g.:
$ echo -e
"user00:Password1234567890:1000:aad3b435b51404eeaad3b435b51404ee:17bd91defd0d2fe234239a5bb90a9595:::\n\
user00:Passwor:d1234567890:1000:aad3b435b51404eeaad3b435b51404ee:17bd91defd0d2fe234239a5bb90a9595:::"|rev|cut
-d: -f7-|rev
user00:Password1234567890
user00:Passwor:d1234567890

The you'll be able to extract passwords by performing a 'cut -d: -f2-'.
E.g.:
$ echo -e
"user00:Password1234567890:1000:aad3b435b51404eeaad3b435b51404ee:17bd91defd0d2fe234239a5bb90a9595:::\n\
user00:Passwor:d1234567890:1000:aad3b435b51404eeaad3b435b51404ee:17bd91defd0d2fe234239a5bb90a9595:::"|rev|cut
-d: -f7-|rev|cut -d: -f2-
Password1234567890
Passwor:d1234567890
Every colon in a password should prevail this operation.

Marek
