Upstream source description

A vulnerability in the Cisco Smart Licensing Utility API of Cisco License On-Prem, formerly Cisco Smart Software Manager On-Prem (SSM On-Prem), could allow an unauthenticated, remote attacker to write arbitrary files to the system or cause a DoS condition on an affected application. This vulnerability is due to improper input validation and a lack of authentication in the management API. An attacker could exploit this vulnerability by sending a crafted request to the affected API. A successful exploit could allow the attacker to modify system files or cause a DoS condition.
