buffer overflowsMany embedded devices used to control critical infrastructure assets are based on the Harvard architecture. This architecture separates data and program memory into independent address spaces, u
接下来看看要如何进入这个漏洞函数,利用IDA的交叉引用功能,可以看到是BufferOverflowStackIoctlHandler函数: int __stdcall BufferOverflowStackIoctlHandler(_IRP *Irp, _IO_STACK_LOCATION *IrpSp) { int v2; // ecx _NAMED_PIPE_CREATE_PARAMETERS *Parameters; // edx v2 = -1073741823; Parameters = IrpSp->...
Exploiting stack buffer overflows[edit] The canonical method for exploiting a stack based buffer overflow is to overwrite the function return address with a pointer to attacker-controlled data (usually on the stack itself).[3][6] This is illustrated with strcpy() in the following example: #inc...
•虚拟机:Windows7 x86 •物理机:Windows 10 x64 •软件:IDA,Windbg,VS2022 漏洞分析 本次实验内容是BufferOverflowStackGS(环境提供的栈溢出一共有两个,一个是普通的,一个是GS保护的) 首先用IDA打开HEVD.sys,搜索BufferOverflowStack,可以看到两个函数:BufferOverflowGSStackIoctlHandler和TriggerBufferOverflow...
对于本文提供的例子代码, 对应到 /RTC1 里的/RTCs 检查失败了,变量 r 被访问了的内存比实际分配的内存要多, 也就是 "stack buffer overflow". 2.4 为什么 Run-Time Check 失败了? 依然看源代码和反汇编代码。在 other.cpp 中, 本该执行 other.cpp 中 Rect 的构造函数: void cpp_func() { Rect r; ...

To this end, I am going to write a series of tutorials on how to write buffer overflows. This is the first entry in this series, and it will cover how to recreate a simple stack based buffer overflow in the Windows application MiniShare 1.4.1. MiniShare 1.4.1 is an older version of...
