Technical description

A vulnerability in the web management interface of Cisco Small Business 220 Series Smart Switches could allow an authenticated, remote attacker to perform a command injection attack. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a malicious request to certain parts of the web management interface. To send the malicious request, the attacker needs a valid login session in the web management interface as a privilege level 15 user. Depending on the configuration of the affected switch, the malicious request must be sent via HTTP or HTTPS. A successful exploit could allow the attacker to execute arbitrary shell commands with the privileges of the root user.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
