Description
A vulnerability in the APIs of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks against the backend database.
This vulnerability is due to insufficient validation of certain parameters that are concatenated directly into an SQL query. An attacker could exploit this vulnerability by sending a crafted request that contains SQL statements to an affected endpoint. A successful exploit could allow the attacker to read arbitrary content from the SQL database and conduct server-side request forgery (SSRF) attacks. To exploit this vulnerability, the attacker must have valid administrative credentials.
