Hi Rajesh,
For the reference the in TAC Case collection, the "work-around" is nicely shown, so this should not be an issue.
For the vulnerability issue in the second doc, you need to make sure that you are at one of the "fixed-in" versions;
4.1
4.1(2)ES55 4.1(3)ES32
4.1(3)SR2 or later
Hope this helps!
Rob
