VCUI-70-000004 - vSphere UI must protect cookies from cross-site scripting (XSS).

Information

Cookies are a common way to save session state over the HTTP(S) protocol. If an attacker can compromise session data stored in a cookie, they are better able to launch an attack against the server and its applications. When a cookie is tagged with the 'HttpOnly' flag, it tells the browser this particular cookie should only be accessed by the originating server. Any attempt to access the cookie from client script is strictly forbidden.

Solution

Navigate to and open:

/usr/lib/vmware-vsphere-ui/server/conf/context.xml

Add the following configuration to the <Context> node:

useHttpOnly='true'

Example:

<Context useHttpOnly='true' sessionCookieName='VSPHERE-UI-JSESSIONID' sessionCookiePath='/ui'>

Restart the service with the following command:

# vmon-cli --restart vsphere-ui
