Microsoft Internet Security and Acceleration (ISA) Server is affected by an HTTP authentication scheme vulnerability. This issue is due to a design error that allows users to authenticate using insecure schemes regardless of a configuration that requires SSL. This issue would potentially lead an unsuspecting user to attempt to authenticate to a web application over insecure channels; attackers may be able to read plaintext authentication credentials even when the affected server is configured to require SSL transactions.
