How to access full street addresses for all Western Digital customers who have performed an RMA.

Using this link: https://websupport.wdc.com/warranty/RMA_PrintLabel.aspx?rma_no=00000000&dp=&lang=en

And replacing the variable rma_no= with a valid 8 digit RMA code will direct you to a page containing a customer's name and full address. This affects all customers in all countries from what I can tell.

Sample valid RMA number ranges:

85XXXXXX

86XXXXXX

The user that found this reported it to Western Digital immediately, and they have so far not taken any action to close this loophole.
