Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in Cisco Wide Area Application Services (WAAS) Software could allow an authenticated, local attacker to gain access to sensitive information on an affected device. The vulnerability is due to improper input validation and authorization of specific commands that a user can execute within the CLI. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to read arbitrary files that they originally did not have permissions to access.
