The following workaround, which was working with build 411 does not work

build 411, we needed to modify the variable "regExp" in the file "x-templates\x-enroll-msie-dn-script.xuda" to be able to submit a certificate request with the apostrophe character, as bellow:

//var regExp = new RegExp( "\[<>\047\042~!@#$^&*|\134;+_\]" );

var regExp = new RegExp( "\[<>\042~!@#$^&*|\134;+_\]" );

The above regex modification is working on build 411 but not working on build 423 because we have fixed vulnerability issue in RCM 6.7 build 420.
