Title
The Security Token Service must limit the number of allowed connections. (Cat II impact)
Discussion
Limiting the number of established connections to the Security Token Service is a basic denial of service protection. Servers where the limit is too high or unlimited can potentially run out of system resources and negatively affect system availability.
Check Content
Connect to the PSC, whether external or embedded. At the command prompt, execute the following command: # xmllint --format /usr/lib/vmware-sso/vmware-sts/conf/server.xml | sed '2 s/xmlns=".*"//g' | xmllint --xpath '/Server/Service/Connector[@port="${bio-custom.http.port}"]/@acceptCount' - Expected result: acceptCount="100" If the output does not match the expected result, this is a finding.
Fix Text
Connect to the PSC, whether external or embedded. Navigate to and open /usr/lib/vmware-sso/vmware-sts/conf/server.xml. Navigate to the <Connector> configured with port="${bio-custom.http.port}". Add or change the following value: acceptCount="100"
