The password-reset form in ServiceNow Orlando provides different responses to invalid authentication attempts depending on whether the username exists.
The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor, which exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not.
