An issue was discovered in Schneider Electric Wonderware Historian 2014 R2 SP1 P01 and earlier. Wonderware Historian creates logins with default passwords, which can allow a malicious entity to compromise Historian databases. In some installation scenarios, resources beyond those created by Wonderware Historian may be compromised as well.
The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.

Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
