Dear Qualys team,



Title:Credit Card Number Pattern Identified in HTML


I think that in this QID there is possibility it is potential vulnerability.

In some case it may detected any information something like item code or mere series of numbers.

I would like to check whether the QG engine normally work.


In this time number of digits is '13' and prefix is '4', so it probably matched by form of Visa.

Actually it was lat/long info.


Is this detection logic checked for prefix and number of digits?

If you cannot make public in the detection logic, so please teach us that.
