MEDIUM 6.1EPSS 1.08%

Does this matter?

Lower severity and a low EPSS score (1.08%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in the logging component of Cisco Identity Services Engine could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks. The vulnerability is due to the improper validation of requests stored in the system's logging database. An attacker could exploit this vulnerability by sending malicious requests to the targeted system. An exploit could allow the attacker to conduct cross-site scripting attacks when an administrator views the logs in the Admin Portal.
