I have a required form field that accepts only a 7 digit numeric value:

<cfinput type="text" maxlength="7" required="yes" validate="numeric" name="empid" message="Please submit a 7 digit numeric value" value="#cookievalue#" size="42" />

I want to prevent users from entering 7 of the same number like 0000000 or 1111111 or 2222222, etc., etc.  

What would be the simplest way to do that ?

One way is with onValidate. Use a regex to ensure the value is exactly 7 digits and to identify repeating numbers

<!--- test value  --->
<cfset cookievalue = repeatString("0",7)>

<script type="text/javascript">
	function isValidEmpId(frm, fld, value) {
		var isSevenDigits = /^(\d){7,7}$/.test(value);
		var isNonRepeating = !/([0-9])\1{6,}/.test(value);
		return isSevenDigits && isNonRepeating;		
      <!--- note, added a mask to remove non-numeric chars typed --->
	<cfinput type="text" name="empid" 
		message="Please submit a 7 digit numeric value" 
		size="10" />
     <input type="submit">
