Summary

  o A vulnerability in the web-based GUI of Cisco IP Phone 6800, 7800, and 8800
    Series with Multiplatform Firmware could allow an authenticated, remote
    attacker to conduct a cross-site scripting (XSS) attack against a user of
    the web-based interface of an affected system.

    The vulnerability is due to insufficient validation of user-supplied input
    by the web-based GUI of an affected system. An attacker could exploit this
    vulnerability by persuading a user of the interface to click a crafted
    link. A successful exploit could allow the attacker to execute arbitrary
    script code in the context of the affected interface or access sensitive,
    browser-based information.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.
