CVE-2023-20119: Cisco Secure Email and Web Manager Reflected XSS Vulnerability
A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Email and Web Manager could allow an unauthenticated, remote attacker to conduct an XSS attack against a user of the interface.
This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. 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.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
