## Overview

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.

## Affected

- `smart_software_manager_on-prem < 8-202112`

## Remediation

Upgrade past the affected range:

- `smart_software_manager_on-prem 8-202112`
