Description

A vulnerability in the web interface of Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an authenticated, remote attacker to elevate privileges on an affected system. This vulnerability is due to the improper transmission of sensitive user information. An attacker could exploit this vulnerability by sending a crafted message to an affected Cisco SSM On-Prem host and retrieving session credentials from subsequent status messages. A successful exploit could allow the attacker to elevate privileges on the affected system from low to administrative. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of System User. Note: This vulnerability exposes information only about users who logged in to the Cisco SSM On-Prem host using the web interface and who are currently logged in. SSH sessions are not affected.
