Summary
o
A vulnerability in the web interface of Cisco Emergency Responder,
Cisco Unified Communications Manager, Cisco Unified Communications Manager

an HTTP request. An attacker could exploit this vulnerability by crafting
an HTTP request that causes the web interface to redirect a request to a
specific malicious URL. This type of vulnerability is known as an open
redirect attack and is used in phishing attacks that get users to
