Summary
A vulnerability in an API of Cisco ISE could allow an authenticated, remote attacker with valid read-only credentials to obtain sensitive information, change node configurations, and restart the node. This vulnerability is due to a lack of authorization in a specific API and improper validation of user-supplied data. An attacker could exploit this vulnerability by sending a crafted HTTP request to a specific API on the device. A successful exploit could allow the attacker to attacker to obtain information, modify system configuration, and reload the device. Note: To successfully exploit this vulnerability, the attacker must have valid read-only administrative credentials. In a single-node deployment, new devices will not be able to authenticate during the reload time.
