Cisco: >> Webex Meetings Security Vulnerabilities
A vulnerability in Cisco Webex Meetings could have allowed an unauthenticated, remote attacker to redirect a targeted Webex Meetings user to an untrusted website. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed.
This vulnerability existed because of insufficient validation of URLs that were included in a meeting-join URL. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by including a URL to a website of their choosing in a specific value of a Cisco Webex Meetings join URL. A successful exploit could have allowed the attacker to redirect a targeted user to a website that was controlled by the attacker, possibly making the user more likely to believe the website was trusted by Webex and perform additional actions as part of phishing attacks.

A vulnerability in the user profile component of Cisco Webex Meetings could have allowed an authenticated, remote attacker with low privileges to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed.
This vulnerability existed because of insufficient validation of user-supplied input to the user profile component of Cisco Webex Meetings. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could have allowed the attacker to conduct an XSS attack against the targeted user.

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.

A vulnerability in the web interface of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.
This vulnerability is due to insufficient CSRF protections for the web interface on an affected system. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to perform arbitrary actions. These actions could include joining meetings and scheduling training sessions.
