CVE-2017-12307

CWE-79

Summary

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.
