App - Système

Cette série d’épreuve vous confronte aux vulnérabilités applicatives principalement liées aux erreurs de programmation aboutissant à des corruptions de zones mémoire.

Les identifiants de connexion sont fournis pour les différents challenges. Le but est d’obtenir des droits supplémentaires en exploitant des faiblesses de programmes et ainsi obtenir un mot de passe permettant de valider chaque épreuve sur le portail.

Prérequis :
- Maitriser un débogueur, par exemple GDB ;
- Avoir des bases en langage assembleur (notamment x86) ;
- Connaitre le langage C.
