CVE-2016-1306

CWE-79

Summary

A vulnerability in the Cisco Fog Director web framework could allow an 
unauthenticated, remote attacker to conduct a cross-site scripting (XSS) 
attack against a user of the web interface of the affected software.

The vulnerability is due to insufficient input validation for some of the 
parameters that are passed to the web server. An attacker could exploit this 
vulnerability by persuading a user to follow a malicious link or by 
intercepting and injecting malicious code into a user request. A successful 
exploit could allow the attacker to execute arbitrary script in the context of
the affected site or access sensitive browser-based information.

Cisco has not released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
