CVE-2022-20654Network attack vector

Script execution via insufficient web-interface input validation

Published Nov 15, 2024 · Updated Nov 15, 2024

Cross-site scripting in the Cisco Webex Meetings web interface allows remote attackers to execute arbitrary script through a crafted link. The cloud-hosted interface insufficiently validates user-supplied input, but Cisco has not disclosed the affected endpoint, parameter, or output operation. Exploitation requires the target user to click the malicious link and grants script execution in the interface context or access to sensitive browser-based information.
