Description

A vulnerability in the REST APIs of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to conduct SQL injection attacks against the session database.

An attacker could exploit this vulnerability by sending a crafted request that contains SQL statements in one of the affected parameters. A successful exploit could allow the attacker to read information from the session database. To exploit this vulnerability, the attacker must have valid administrative credentials.
