CVE-2016-1331

CWE-79

Summary

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

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

Cisco has not released software updates that address this vulnerability. 
Workarounds that mitigate this vulnerability are not available.
