Does this matter?

Lower severity and a low EPSS score (5.12%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to perform a directory traversal attack on an affected device. The vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to bypass Cisco FMC Software security restrictions and gain access to the underlying filesystem of the affected device.
