A vulnerability in the authentication system of Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an unauthenticated, remote attacker to change the password of any user, including administrative users. This vulnerability is due to improper implementation of the password-change process. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow an attacker to access the web UI or API with the privileges of the compromised user.
