Cisco Security Advisory
-
An issue in the Password Policy settings of Cisco Identity Services Engine (ISE) could allow an administrator to use expired credentials to gain access to the web management interface.
When the Password Lifetime setting for the administrator password policy is used to set the password to expire, the password does not expire. As a result, an administrator could use expired credentials to log in to the web management interface and have the same level of privileges as before the password expired. No additional privileges would be gained, and valid credentials would be required.

While this workaround has been deployed and was proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.
