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 debug logging function of Cisco Duo Authentication Proxy could allow an authenticated, high-privileged, remote attacker to view sensitive information in a system log file. This vulnerability is due to insufficient masking of sensitive information before it is written to system log files. An attacker could exploit this vulnerability by accessing logs on an affected system. A successful exploit could allow the attacker to view sensitive information that should be restricted.
