"According to its self-reported version number, the installation of
Cisco Unified MeetingPlace Web Conferencing hosted on the remote web
server is potentially affected by a security bypass vulnerability due
to the lack of validation of the current password and HTTP session ID
during a password change request. A remote attacker can exploit this,
via a crafted HTTP request, to change the password of an arbitrary
user.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number. Additionally,
the coarse nature of the version information Nessus gathered is not
enough to confirm that the application is vulnerable, only that it
might be affected.");
