========================= About this PoC =========================================
This exploit is a proof-of-concept exploit which demonstrates how to exploite java native vulnerabilities with Java-JIT-Spray technique. It is developped and only tested on Windows 7 enterprise 32 bits.
This vulnerability was discovered by Jushua J Drake (jduck) of accuvantlabs. For the detail of this vulnerability, see: http://blog.accuvantlabs.com/sites/default/files/Papers/Pwn2Own%202013%20-%20Java%207%20SE%20Memory%20Corruption.pdf
For more details of java jit spray technique, see my slides at SyScan360: http://aj43xnbacx.l31.yunpan.cn/lk/QGb98dgpj74YJ
========================= How to compile ======================================
To compile the source code, you need jdk and python installed.
Make sure "javac" and "python" is in your path environments.
Check out the source under "src", open a terminal and change the dir to the "src" folder.
run the following command: make.bat 40 60
Where the first parameter "40" means each class file contains 40 JIT functions, and the second parameter "60" means we will spray totally 60 classes.
After running the command, a jar file named "Exploit.jar" will be generated within the same folder.
========================= How to test =========================================
Environment: JRE 7u17 + Windows 7 32bits (english version)
Note: The jit-spray takes some time (7 ~ ?? seconds depends on your test machine). Please wait with patient while spraying :)
