Introduction The vulnerability reads as follows: Stack-based buffer overflow in the CmpWebServer component in 3S CoDeSys 3.4 SP4 Patch 2 and earlier, as used on the ABB AC500 PLC and other products, allows remote attackers to execute arbitrary code via a long URI to TCP port 8080. The final idea of this article is to reproduce and detail the process by which the vulnerability can be detected a..
Welcome everybody. The idea of this website is to provide detailed tutorials on Linux and Windows exploit development. The content will be in English to reach a wider range of readers. My English is not very high but I will try as much as possible to publish with good English :)The web will mainly have two categories:In Windows exploiting category I will use CVE to exploit the vulnerability of..
Writeup - pwnable.kr Sabiendo que tenemos un overflow y la dirección de retorno en el stack, podríamos escribe en el buffer donde contiene los primeros 4 bytes del nombre que introducimos. Deberemos escaping primero en ese buffer cuando nos pregunta por cual es nuestro nombre, los opcodes de jmp rsp. Segundo aprovecharemos el overflow para escribir en la dirección de retorno justo la dirección d..
