CVE-2018-15403
CWE-601

Summary

  o 
    A vulnerability in the web interface of Cisco Emergency Responder,
    Cisco Unified Communications Manager, Cisco Unified Communications Manager
    IM & Presence Service, and Cisco Unity Connection could allow an
    authenticated, remote attacker to redirect a user to a malicious web page.

    The vulnerability is due to improper input validation of the parameters of
    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
    unknowingly visit malicious sites.

    There are no workarounds that address this vulnerability.
