The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/1042/info The registry value HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Common Startup specifies the shared startup folder for all users on a system. This key is set to be writeable by any authenticated user. Therefore, any user could specify a folder with a shortcut to a program of their choice that will be run any time a user logs in, at the privilege level of that user. Example: On a Domain Controller, a batch file containg the following commands: -- net user attacker /add /domain net group administrators attacker /add /domain -- could be put into the folder c:\hackstartup. Then the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Common Startup could be set to the string "c:\hackstartup". The next time an administrator logs on to that machine, the 'attacker' account will be created and added to the Administrators group on the PDC of the domain.
