Name of the Vulnerable Software and Affected Versions: Cisco IOS XE Wireless Controller software for the Catalyst 9000 Family of switches (affected versions not specified)

Description: A vulnerability in the web-based management interface could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against another user of the interface. The issue is due to insufficient validation of user-supplied input. An attacker could exploit this by authenticating as a high-privileged user, adding configurations with malicious code, and persuading another user to click on it. A successful exploit could allow the attacker to execute arbitrary script code or access sensitive browser-based information.

Recommendations: For Cisco IOS XE Wireless Controller software for the Catalyst 9000 Family of switches, update to a version that includes the software updates released by Cisco to address this vulnerability. As a temporary workaround, consider restricting access to the web-based management interface to minimize the risk of exploitation.
