Unauthorized system access via exposed stored credentials

Published Sep 2, 2021 · Updated Nov 7, 2024

Information disclosure in the CLI of Cisco Prime Infrastructure before 3.8 allows local users to access sensitive stored credentials. The CLI stores authentication material on the underlying file system without sufficient protection against an authenticated local account. Access to that material enables forged authentication requests and unauthorized access to the affected system.
