Summary
Cisco Identity Services Engine versions prior to 2.0 contain a vulnerability
that could allow a low-privileged authenticated, remote attacker to access
specific web resources that are designed to be accessed only by
higher-privileged administrative users.
The vulnerability occurs because specific types of web resources are not
correctly filtered for administrative users with different privileges. An
attacker could exploit this vulnerability by authenticating at a
low-privileged account and then accessing the web resources directly. An
exploit could allow the attacker to access web pages that are reserved for
higher-privileged administrative users.
Cisco has released software updates that address these vulnerabilities. There
are no workarounds that address this vulnerability.
