Vulnerability from github – Published: 2026-10-07 18:32 – Updated: 2026-10-07 18:32

Details

This vulnerability is due to improper validation of user-supplied content within configurations that are submitted to the web-based management interface. An attacker could exploit this vulnerability by updating configurations within the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. To exploit this vulnerability, the attacker must have valid administrative credentials. Because only an attacker who already holds system administrator privileges can exploit the vulnerability, the only additional privileges gained include the ability to turn off the system, which an administrative user could not normally do.

Severity

4.9 (Medium)

Title

Cisco Smart Software Manager On-Prem Command Injection Vulnerability

Summary

A vulnerability in the web-based user interface of Cisco License On-Prem, formerly Cisco Smart Software Manager On-Prem (SSM On-Prem), could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system. This vulnerability is due to improper validation of user-supplied content within configurations that are submitted to the web-based management interface. An attacker could exploit this vulnerability by updating configurations within the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. To exploit this vulnerability, the attacker must have valid administrative credentials. Because only an attacker who already holds system administrator privileges can exploit the vulnerability, the only additional privileges gained include the ability to turn off the system, which an administrative user could not normally do.
