VCLD-67-000022
(in versions v1 r3 through v1 r2)
Title
VAMI must prevent hosted applications from exhausting system resources. (Cat II impact)
Discussion
Most of the attention to denial-of-service (DoS) attacks focuses on ensuring that systems and applications are not victims of these attacks. However, these systems and applications must also be secured against use to launch such an attack against others. A variety of technologies exist to limit or, in some cases, eliminate the effects of DoS attacks. Limiting system resources that are allocated to any user to a bare minimum may also reduce the ability of users to launch some DoS attacks. One DoS mitigation is to prevent VAMI from keeping idle connections open for too long.
Check Content
Note: The below command must be run from a bash shell and not from a shell generated by the "appliance shell". Use the "chsh" command to change the shell for the account to "/bin/bash". At the command prompt, execute the following command: # /opt/vmware/sbin/vami-lighttpd -p -f /opt/vmware/etc/lighttpd/lighttpd.conf|grep "server.max-keep-alive-idle" Expected result: server.max-keep-alive-idle = 30 If the output does not match the expected result, this is a finding.
Fix Text
Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf file. Add or reconfigure the following value: server.max-keep-alive-idle = 30
