5.4/10

Summary

A vulnerability in the web-based management interface of Cisco Unified Customer Voice Portal (CVP) could allow an authenticated, remote attacker to perform a cross-site scripting (XSS) attack against a user. This vulnerability is due to insufficient input validation of a parameter that is used by the web-based management interface. An attacker could exploit this vulnerability by persuading a user to click a malicious link. A successful exploit could allow the attacker to execute arbitrary code in the context of the interface, access sensitive, browser-based information, or cause an affected device to reboot under certain conditions.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
