| Description | ||||
| Leaving sessions open indefinitely is a major security risk. An attacker can easily use an already authenticated session to access the hosted application as the previously authenticated user. By closing sessions after a set period of inactivity, the web server can make certain that those sessions that are not closed through the user logging out of an application are eventually closed.

Check Text (C-259116r935252_chk)
At the command prompt, run the following command:
# xmllint --format /usr/lib/vmware-vsphere-ui/server/conf/web.xml | sed 's/xmlns=".*"//g' | xmllint --xpath '/web-app/session-config/session-timeout' -
Example result:
<session-timeout>30</session-timeout>
If the value of "session-timeout" is not "30" or less, or is missing, this is a finding.
