WebEx Meeting Information Disclosure Vulnerability in meetinginfo.do
CVE ID: CVE-2014-2199
Release Date: 2014 May 15 18:19 UTC (GMT)
Last Updated: 2014 May 15 21:37 UTC (GMT)
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
