Description
The web interface of the Vertiv Avocent UMG-4000 version 4.2.1.19 is vulnerable to reflected XSS in an HTTP POST parameter. The web application does not neutralize user-controllable input before displaying to users in a web page, which could allow a remote attacker authenticated with a user account to execute arbitrary code.
