No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) could allow an authenticated, 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 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 browser of the targeted user or access sensitive, browser-based information.
