我正试图通过内核读出另一个进程的内存 模式驱动。它正在工作,我正在将驱动程序注入到空间中 另一个让它工作的驱动程序(或者只能启用测试模式)。

然而,它运作良好,但是当给出错误的地址时,我会得到一个 BSOD。

以下是有关BSOD的一个示例的信息:

SYSTEM_SERVICE_EXCEPTION (3b)
An exception happened while executing a system service routine.
Arguments:
Arg1: 00000000c0000005, Exception code that caused the bugcheck
Arg2: ffffe000d509c720, Address of the instruction which caused the bugcheck
Arg3: ffffd00026053db0, Address of the context record for the exception that 
caused the bugcheck
Arg4: 0000000000000000, zero.

当我将驱动程序注入另一个驱动程序时,符号等不可能 解决。还有一些其他信息:

现在我正在做什么:我给驱动程序4个值并有一个全局缓冲区 将读出值写入:

char buf [5000]; NTSTATUS DevioctlDispatch(      struct _DEVICE_OBJECT * DeviceObject中,      Inout struct _IRP * Irp     ) 我在驱动程序中所做的一切都是多个__try __catch / __除了/ __ finally块,我希望我能抓错读 出局... 我正在获取进程句柄,然后将它(在ProbeForRead之后)传递给 RtlCopyMemory:

__try
{
    KeAttachProcess(myprocess);
    ProbeForRead((void*)address, len, 1);
    RtlCopyMemory((void*)buf, (void*)address, len);
    KeDetachProcess();
}
__except(EXCEPTION_EXECUTE_HANDLER)
{
    DbgPrint("Exception.\n");
    status = STATUS_INVALID_PARAMETER;
    KeDetachProcess();
    return status;
}

我经常这样做,但我确信无论如何都要分离。

我应该使用KeStackAttachProcess吗? BSOD来自哪里? 我错误地抓错了吗?谢谢!是的,我正在阅读用户空间应用程序。

1 个答案:

答案 0 :(得分:0)

由于我还没有有效的证书,我在vboxdrv中使用漏洞加载我的驱动程序(为了不在测试系统上)。但我发现,它不支持SEH。因此,我的尝试/除了没有任何正确的...只需等待我的证书或使用测试模式。
