Does this matter?

Lower severity and a low EPSS score (0.48%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in the REST API of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to conduct SQL injection attacks against the monitoring database. This vulnerability is due to insufficient validation of specific parameters that are then concatenated into an SQL statement. 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 monitoring database. To exploit this vulnerability, the attacker must have valid administrative credentials.
