Summary

  * A vulnerability in the Web Admin Interface of Cisco Meeting Server could
    allow an authenticated, remote attacker to cause a denial of service (DoS)
    condition.

    The vulnerability is due to insufficient validation of incoming HTTP
    requests. An attacker could exploit this vulnerability by sending a
    crafted HTTP request to the Web Admin Interface of an affected Cisco
    Meeting Server. A successful exploit could allow the attacker to restart
    the system, terminating all ongoing calls and resulting in a DoS condition
    on the affected product.

    There are no workarounds that address this vulnerability.
