ifconfig usually residence in /sbin (some GNU/Linux distribution are in the 
migration path of moving it to /usr/sbin), this directory  is never in a 
normal users or a daemon users $PATH, so you need to give the whole path to 
this binary to be able to run it.

By default the file is executional by all users, but someone may have changed 
permissions or setup ACL rules with for example SELinux.
