Il s'agit d'un petit outil d'analyse des vulnérabilités Web créé par Bi She l'année dernière. Il cible principalement les vulnérabilités d'injection SQL simple, l'injection aveugle SQL et les vulnérabilités XSS. Le code a été lu par un maître étranger sur github (j'ai entendu dire qu'il en faisait partie). des auteurs de SMAP) Le code source des deux gadgets a été écrit par moi-même sur la base des idées qu'il contient. Vous trouverez ci-dessous les instructions d'utilisation et le code source.
1. Mode d'emploi :
1. Environnement d'exploitation :
Interface de ligne de commande Linux Python2.7
2. >
Vim scanner//Créer un fichier nommé scanner--url URL analysée
--data Paramètres de la méthode de requête POST
--cookie En-tête de requête HTTP Cookie value
--user-agent HTTP request header User-Agent value
--random-agent S'il faut utiliser le déguisement du navigateur
--referer L'interface de couche supérieure de l'URL cible
--proxy HTTP Demander la valeur du proxy d'en-tête
