Check: VCUI-67-000018
VMware vSphere 6.7 UI Tomcat STIG:
VCUI-67-000018
(in versions v1 r3 through v1 r1)
Title
vSphere UI must limit the number of allowed connections. (Cat II impact)
Discussion
Limiting the number of established connections is a basic denial-of-service protection and a best practice. Servers where the limit is too high or unlimited can potentially run out of system resources and negatively affect system availability.
Check Content
At the command prompt, execute the following command: # xmllint --format /usr/lib/vmware-vsphere-ui/server/conf/server.xml | sed '2 s/xmlns=".*"//g' | xmllint --xpath '/Server/Service/Connector[@port="${http.port}"]/@acceptCount' - Expected result: acceptCount="300" If the output does not match the expected result, this is a finding.
Fix Text
Navigate to and open /usr/lib/vmware-vsphere-ui/server/conf/server.xml. Navigate to the <Connector> configured with port="${http.port}". Add or change the following value: acceptCount="300"
