A vulnerability in the reclaim host role feature of Cisco Webex Meetings and Cisco Webex Meetings Server could allow an authenticated, remote attacker to take over the host role during a meeting. This vulnerability is due to a lack of protection against brute forcing of the host key. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Webex Meetings Server site. A successful exploit would require the attacker to have access to join a Webex meeting, including applicable meeting join links and passwords. A successful exploit could allow the attacker to acquire or take over the host role for a meeting.4.3CVE-2021-1410ciscocisco webex meetings+1

A vulnerability in the distribution list feature of Cisco Webex Meetings could allow an authenticated, remote attacker to modify a distribution list that belongs to another user of their organization. The vulnerability is due to insufficient authorization enforcement for requests to update distribution lists. An attacker could exploit this vulnerability by sending a crafted request to the Webex Meetings interface to modify an existing distribution list. A successful exploit could allow the attacker to modify a distribution list that belongs to a user other than themselves.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.4.7CVE-2021-1310ciscocisco webex meetings+1

A vulnerability in the user interface of Cisco Webex Meetings and Cisco Webex Meetings Server Software could allow an authenticated, remote attacker to inject a hyperlink into a meeting invitation email. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by entering a URL into a field in the user interface. A successful exploit could allow the attacker to generate a Webex Meetings invitation email that contains a link to a destination of their choosing. Because this email is sent from a trusted source, the recipient may be more likely to click the link.4.3CVE-2021-1467ciscocisco webex meetings+1

A vulnerability in the application integration feature of Cisco Webex Software could allow an unauthenticated, remote attacker to authorize an external application to integrate with and access a user's account without that user's express consent. This vulnerability is due to improper validation of cross-site request forgery (CSRF) tokens. An attacker could exploit this vulnerability by convincing a targeted user who is currently authenticated to Cisco Webex Software to follow a link designed to pass malicious input to the Cisco Webex Software application authorization interface. A successful exploit could allow the attacker to cause Cisco Webex Software to authorize an application on the user's behalf without the express consent of the user, possibly allowing external applications to read data from that user's profile.4.3CVE-2015-6384ciscowebex_meetings
