Summary

  o A vulnerability in the web framework of Cisco Emergency Responder could
    allow an authenticated, remote attacker to conduct a cross-site scripting
    (XSS) attack against a user of the web-based management interface.

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

    There are no workarounds that address this vulnerability.
