i noticed easy spotable differences to figure installed version is vulnerable or not:
So u click "Bing Rewards" button (the one that shows bing points):
if it shows pictures related to available offers in its context window- its probably not vulnerable version.
if it is needed to click only once to get the offer in that context window- its probably not vulnerable version.
and if it shows no pictures and u actually have to click twice the offer (first click just expands it)- it is double points exploitable.
