REDHAT-BUG-475998: Medium severity red hat certificate system vulnerability
During the internal code review, it was discovered that Red Hat Certificate System / Dogtag Certificate System does not properly verify challenge response received during the enrollment of new security token.
If keys are generated on the token during the enrollment, TPS correctly verifies that the requestor possesses the private key, but fails to verify that the key really exists on the token and is not only in software.
An attacker with access to blank token known to TPS component and with privilege to perform enrollments of new tokens could use this flaw to successfully finish enrollment procedure with the software generated key instead of the one stored in the token.
Affected versions: Red Hat Certificate System 7.1, 7.2, 7.3 Dogtag Certificate System 1.0
