Summary

  * A vulnerability in the session identification management functionality of
    the web-based management interface for Cisco Meeting Server could allow an
    unauthenticated, local attacker to hijack a valid user session identifier.

    The vulnerability exists because the affected application does not assign
    a new session identifier to a user session when a user authenticates to
    the application. An attacker could exploit this vulnerability by using a
    hijacked session identifier to connect to the application through the
    web-based management interface. A successful exploit could allow the
    attacker to hijack an authenticated user's browser session.

    There are no workarounds that address this vulnerability.
