EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

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.

source: https://www.securityfocus.com/bid/993/info The Windows Autorun feature was designed to allow an executable and an icon to be specified for any piece of removable media. Upon insertion, the icon would be displayed for the drive, and the executable would automatically run. This feature also applies to fixed and networked drives however, making it much easier to abuse. Any user with write access to the root of a logical drive can install an executable and specify it in an autorun.inf file. Anytime that drive is accessed later, the code will run with the privileges of the currently logged in user. This could be used in privilege escalation attacks. As a test, make an autorun.inf file in C:\ with the following contents: [autorun] open=<path>notepad.exe If your system is vulnerable, 'opening' C: should result in notepad strating up. Also, if you right-click on C: you should the Autoplay option in the drop-down menu. The following exploit has been provided by Nelson Brito <nelson@secunet.com.br>:Step by Step: 1 - find a admin's mount point(a.k.a. home directory); 2 - place the autorun.inf and autorun2.exe on there; 3 - drop the admin's connection(use your prefered DoS tool); 4 - try to connect as user nelson and password nelson; 5 - BINDO, you are now a member of "Administrators" group(Stand Alone Servers) or "Domain Admins" gourp(PDC Servers).
