Summary
A vulnerability in Cisco WebEx Business Suite (WBS) could allow an
unauthenticated, remote attacker to use enumerated meeting identifiers to
obtain confidential information. The vulnerability is due to meeting
identifiers that are not randomly generated and may be enumerated. This may
result in the disclosure of information such as the meeting title, meeting
organizer, time, date, and duration of the meeting. If the meeting organizer
does not require a password to attend the meeting or event, the meeting
number is also returned and may be used to attend a meeting that is in
progress. Even if a password is configured for a meeting, it is not required
for participation on the audio bridge.
Cisco has deployed software updates to the cloud services that address this
vulnerability.
Vulnerable Products
The vulnerability disclosed in this document affected the Cisco WebEx
Business Suite (WBS27, WBS28, and WBS29):
Cisco WebEx Business Suite (WBS29) prior to 29.5.1.12
Cisco WebEx Business Suite (WBS28) prior to T28L10NSP12EP13.18 (28.12.13.18)
Cisco WebEx Business Suite (WBS27) prior to T27L10NSP32EP31.16 (27.32.31.16)
To determine whether a Cisco WebEx meeting site is running an affected version
of the WebEx client build, users can log in to their Cisco WebEx meeting site
and go to the Support > Downloads section. The version of the WebEx client
build will be displayed on the right side of the page under the appropriate
center (such as "About Support Center" or "About Event Center"). See "Affected
Products" for details.
Alternatively, version information for the Cisco WebEx meeting client can be
accessed in the Cisco WebEx meeting client. Version information for the Cisco
WebEx meeting client on Windows and Linux platforms can be viewed by choosing
Help > About Cisco WebEx Meeting Center. Version information for the Cisco
WebEx meeting client on Mac platforms can be viewed by choosing Meeting Center
> About Cisco WebEx Meeting Center.
Workarounds
Meeting organizers should require a password when scheduling WebEx meetings or
events. The site administrator for the WebEx service can configure site-wide
parameters to require passwords for all meetings. After all expected attendees
have joined the meeting, the meeting host may lock the meeting, preventing
others from attending by selecting the Restrict Access option from the
Meeting menu.
If the title of the meeting contains sensitive information, the meeting
should be scheduled as an unlisted meeting. The site administrator for the
WebEx service can configure site-wide parameters to prevent users from
scheduling listed meetings and require users to enter a password when
scheduling meetings or events to prevent unauthorized disclosure of meeting
numbers.
