CVE-2021-1310 Information

Description

A vulnerability in the web-based management interface of Cisco Webex Meetings could allow an unauthenticated remote attacker to redirect a user to an untrusted web page bypassing the warning mechanism that should prompt the user before the redirection. This vulnerability is due to improper input validation of the URL parameters in an HTTP request. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to redirect a user to a malicious website bypassing the Webex URL check that should result in a warning before the redirection to the web page. Attackers may use this type of vulnerability known as an open redirect attack as part of a phishing attack to convince users to unknowingly visit malicious sites.
