Code injection derives from a software vulnerability that allows a malicious user to inject custom code into the server engine. In recent years, there have been a great number of such exploits targeting web applications. In this paper we propose an approach that prevents a specific kind of code injection attacks known as xpath injection in a novel way. To detect an attack, our scheme uses locat...

Many mechanisms have been proposed and deployed to prevent exploits against software vulnerabilities. Among them, W⊕X is one of the most effective and efficient. W⊕X prevents memory pages from being simultaneously writable and executable, rendering the decades old shellcode injection technique infeasible. In this paper, we demonstrate that the traditional shellcode injection attack can be reviv...

The new DLL injection method and its variants can prevent the injected process from calling common system API to load module so that malicious is invisible LDR linked list of process. Traditional detection methods have low accuracy in forensic attacks. To solve this problem, paper proposes a code covert memory page algorithm based on structure reverse analysis named MRCIF. First, physical pages...

The contribution of this paper is twofold: (1) a novel fault injection attack against AES, based on a new fault model, is proposed. Compared to state-of-the-art attacks, this fault model advantage is to relax constraints on the fault location, and then reduce the a priori knowledge on the implementation. Moreover, the attack algorithm is very simple and leaves room for optimization with respect...

We study the strength of certain obfuscation techniques used to protect software from reverse engineering and tampering. We show that some common obfuscation methods can be defeated using a fault injection attack, namely an attack where during program execution an attacker injects errors into the program environment. By observing how the program fails under certain errors the attacker can deduc...

Injection vulnerabilities pose a major threat to applicationlevel security. Some of the more common types are SQL injection, crosssite scripting and shell injection vulnerabilities. Existing methods for defending against injection attacks, that is, attacks exploiting these vulnerabilities, rely heavily on the application developers and are therefore error-prone. In this paper we introduce CSSE,...
