Hacking Oracle

Simply annoying. You know that gorgeous message saying “memory couldn’t be wrrrrriten press OK to exit or Cancel to debug…”. I thought that TNSLISTENER of Oracle9 could say something more…My all classical reapairments (like reboot, reinstall) came to nought. Well I tried to press cancel and see disassembler complaining that memory around zero can’t be read. Of Course ! edx was 0

mov ecx,dword ptr [edx+578h]

I put edx=eax (eax seemed to be valid address) and debugger was at least for a while satisfied until he reached another address where I have used similar approach to get rid of non valid addresses…and I was able to login into my databse ! (but the problem was to do it all the time I run sqlplus;( At the end of the day I found it was something with ws32_2.dll actually windowsockets and its LSP. I used tool called WinsockXPFix.exe and restarted my laptop. All is now runing fine… But believe me, I was ready to use IDA dissasembler and permanently modify the orantcp9.dll 😉 [a good tool for ‘assembler scripting’;]

P2V port

If you are user of VMWare workstation, you may be interested of way how to migrate your existing physical machine into the virtual one. You may either buy VMWare P2V assistant starter edition or you may use the workflow for not less than trying that;) I made successful experimental migration with following configuration: OS: Windows XP professional SP1, VMware 4.0, ‘Image maker’: PowerQuest DriveImage 7.0. Note that later VMWares doesn’t allow to run PowerQuest recovery utility ! (but waste your time and try it to prove it)
1. Make your HDD image by running Drive Image on your physical machine
2. Put the image on some acessible network or external HDD which can be seen by PQ Recovery utility
3. Configure you VMWare virtual machine for target OS with disk and nework specs.
4. Boot inside VMWare PQ Recovery utility and find your drive image
5. Run restore (I do not remember the right toggles checked in…I made it in October..leaving defaults should work)
