A flaw was found in the CloudForms account configuration when using VMware. By default, a shared account is used that has privileged access to VMRC (VMWare Remote Console) functions that may not be appropriate for users of CloudForms (and thus this account). An attacker could use this vulnerability to view and make changes to settings in the VMRC and virtual machines controlled by it that they should not have access to.

Demo Examples

Insufficient Session Expiration

CWE-613

The following snippet was taken from a J2EE web.xml deployment descriptor in which the session-timeout parameter is explicitly defined (the default value depends on the container). In this case the value is set to -1, which means that a session will never expire.


               
</web-app>
</session-config>
<session-timeout>-1</session-timeout>
