Description

A vulnerability in the web-based management interface of Cisco License On-Prem, formerly Cisco Smart Software Manager On-Prem (SSM On-Prem), could allow an unauthenticated, remote attacker to gain unauthorized access to an affected application. This vulnerability is due to improper checks during the password reset process. An attacker could exploit this vulnerability by sending a malicious request to the web-based management interface. A successful exploit could allow the attacker to reset the password of an arbitrary account, including high-privileged administrative user accounts, possibly allowing the attacker to gain unauthorized access to the application as any user.
