Only the value can be retreived form the cookie scope. To get anything else you would need to reach into getPageContext() and get the request so you can fish out the actual cookie objects.
<cfset cookies = getPageContext().getRequest().getHTTPRequest().getCookies() />
<cfloop array="#cookies#" index="cookieIndex">
<cfoutput>
Name: #cookieIndex.getName()#<br />
Value: #cookieIndex.getValue()#<br />
Expires: #cookieIndex.getMaxAge()#<br />
Domain: #cookieIndex.getDomain()#<br />
Path: #cookieIndex.getPath()#

</cfoutput>
</cfloop>
