There are a lot of variables which can cause the compilation to fail, such as: syntax, libraries, host and target architectures, installed software used for compiling code and a lot more. When compiling exploits for different architectures and operating systems many errors can occur. Let’s see how we can run the exploit from a Meterpreter session. This means we can also run this exploit from command line shell, such as Meterpreter.
This exploit actually spawns a new shell in the current shell where it was launched from instead of a new shell in a new window. I686-w64-mingw32-gcc 40564.c –o exploit.exe –lws2_32Īs we can see the whoami command returns a privileged user before executing the exploit and system user after. The following command will compile the Windows 7 afd.sys privilege escalation exploit: Use the following command to compile the afd.sys exploit for Windows 32 bit: Let’s start with downloading the exploit from Exploit-db: Let’s have a look at how we can compile 32 bit Windows exploits.
#Installing mingw w64 64 Bit#
Even though Mingw-w64 was developed for the much needed 64 bit support we can also compile 32 bit Windows exploits. This version of the Windows operating system contains a vulnerability in the Ancillary Function Driver (AFD) which allows an elevation of privilege for an authenticated non administrative user. For this tutorial we will be compiling a Windows exploit written in c to exploit CVE-2011-1249 (MS11-046) vulnerability in Windows 7 SP0 x86. Now that we have Mingw-w64 installed we can start to compile Windows exploits on Kali Linux. Cross compiling Windows exploits with Mingw-w64
#Installing mingw w64 update#
With the right repositories in the sources.list file you need to run apt-get update and then run the installation command for the Mingw-w64 package again. You can find the repositories for different versions of Kali Linux on the following page: Make sure you have the correct repositories in this file. To solve this issue make sure you have the right repositories in the sources.list file.
#Installing mingw w64 install#
Sometimes you get a Unable to locate package mingw-w64 error when trying to install the mingw-w64 package and get something apt-get install mingw-w64 Downloading and installing Mingw-w64 may take a little while to complete.
Type y for yes to confirm and continue the Mingw-w64 installation process. Once this is complete you should have a build of libobjc2 in the build dir.Use apt-get install mingw-w64 to install Mingw-w64 on your Kali host.
