"According to its self-reported version, Cisco Secure Email Gateway Cross-Site Scripting is affected by a vulnerability.

  - A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Email and
    Web Manager and Secure Email Gateway could allow an authenticated, remote attacker to conduct a stored
    cross-site scripting (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. To exploit this vulnerability, the attacker must have valid credentials for a user account
    with at least the role of Operator. (CVE-2025-20180)

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
