CVE-2023-20104
Cisco Webex App for Web Cross-Site Scripting (XSS) Vulnerability
Description
A vulnerability in the file upload functionality of Cisco Webex App for Web could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending an arbitrary file to a user and persuading that user to browse to a specific URL. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
