Cisco · Cisco Webex Meetings · CVE-2021-40128
**Name of the Vulnerable Software and Affected Versions**
Cisco Webex Meetings (affected versions not specified)
**Description**
A vulnerability in the account activation feature of Cisco Webex Meetings could allow an unauthenticated, remote attacker to send an account activation email with an activation link that points to an arbitrary domain. This is due to insufficient validation of user-supplied parameters, such as `user-supplied parameters`. An attacker could exploit this vulnerability by sending a crafted HTTP request to the "account activation page" of Cisco Webex Meetings. A successful exploit could allow the attacker to send to any recipient an account activation email that contains a tampered activation link, which could direct the user to an attacker-controlled website.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
