I am working through some buffer overflow exploit examples and have written a basic vulnerable C app to test with: (target and attacker is the same Kali 2 machine and have run "echo "0" > /proc/sys/kernel/randomize_va_space") #include<stdio.h>#include<string.h>#include<stdlib.h>intm...
memcpy(buffer+60, shellcode, sizeof(shellcode)-1); strcat(command, "\'"); system(command); //run exploit } You can see that shellcode is combined with NOP sled and return address which should point to that NOP sled. The author uses address of a local variable i as a point of ref...
Buffer overflow attacks have been there for a long time. It still exists today partly because of programmers carelessness while writing a code. The reason I said ‘partly’ because sometimes a well written code can be exploited with buffer overflow attacks, as it also depends upon the dedication...
This is an example of the stack overflow ROP exploit, which we used to call our code (which also can be harmful). Let’s consider how we can create a functional defense against such attacks. Read also DDoS Attacks: Technique Overview and Mitigation Best Practices ...
In both cases, a successful attack results in malware being uploaded to the targeted server. However, unlike RFI, LFI assaults aim to exploit insecure local file upload functions that fail to validate user-supplied/controlled input. As a result, malicious character uploads and directory/path trave...

An attacker wishing to execute SQL injection manipulates a standard SQL query to exploit non-validated input vulnerabilities in a database. There are many ways that this attack vector can be executed, several of which will be shown here to provide you with a general idea about how SQLI works...
The security of the machine is undermined, e.g., when the voter visits the attacker's webpage. In essence, we exploit Adobe Acrobat/Reader's vulnerabilities to in-stall a malicious browser extension on the voters' ma-chines. Such an extension provides an opportunity for an attacker which ...
To explain this a bit better, the exploit will work if the BSS segment is writable. Declaring a string like this makes it, according to the C standard, const. Writing to a static string is undefined behaviour, so it can work or not. ...
