That is broken. You are looking up a literal "*" in clientpasswd and
returning $1 on success. You need to lookup the given username (as
present in variable $1) and return the value keyed to this entry instead.

This might do what you want to:
cram:
  driver = cram_md5
  public_name = CRAM-MD5
  server_secret = ${lookup{$1}lsearch{/etc/exim/clientpasswd}{value}fail}
  server_set_id = $1
