During a PCI scan, the report returned the following message:
"Common DNS misconfiguration can lead to "same site" scripting."
If a user adds a DNS record for localhost in their domain, it can cause PCI scans to trigger a failure for the DNS record.
For example, domain.com or the domain with the issue would have the following DNS record:
localhost IN A 127.0.0.1
Edit the DNS via DNS Zone Manager to remove the "localhost" report pointing to "127.0.0.1".
