I'm fairly sure I get what you're describing.  Problem is, given you've got a
single shared account on the CentOS machine, any user is free to run any old
key logger or put modified binaries in the path.  It's just plain not secure,
and it doesn't matter that the machine has now permissions to the network.

Shared accounts are a bad idea from almost every angle.
