CWE-259: Use of Hard-coded Password - CVE-2015-0972

ProctorCache prior to version 2015.1.17 requires authentication to perform administrative tasks. However, the authentication consists of a hard-coded administrative password, which is not unique per installation, and cannot be changed.

An attacker on the local network can use the credentials to interrupt a test session and perform administrative tasks such as canceling tests or deleting users. According to Pearson, the actual test data is encrypted and not immediately accessible by an administrator.

Pearson has released ProctorCache version 2015.1.17 to address this issue by allowing the password to be changed. Affected users will be notified directly by Pearson of the update, and should update their software to version 2015.1.17 or later as soon as possible. The location of the upgrade as well as instructions for changing the ProctorCache password will be provided for download in the notification to existing customers.
