A vulnerability in the web framework of Cisco Small Business Managed Switches software could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the web interface of an affected system.
The vulnerability is due to insufficient input validation of parameters that are passed to the web server of the affected system. An attacker could exploit this vulnerability by convincing a user to follow a malicious link or by intercepting and injecting code into a user request. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web interface or allow the attacker to access sensitive browser-based information.
There are no workarounds that address this vulnerability.
