hi Roman:
I too observed the same thing. i am running a windows 2K, SP4. i found that base address of UMPNPMGR.DLL is 0x767a0000. however, when i run the attack with this address, the target machine got rebooted (a crash). this may be, because umpnpmgr.dll is a part of "service.exe", therefore, on failure, it reboots. but with the unchanged base address, it worked perfectly. so now the same code can be used for DoS also!!!

Hi,

I tested existing exploits for PnP bug on my W2k SP4 machine (Spanish)
and they didn't work ("services" process is crashing but I got no
shell). So I did a quick review with Olly and I realized that
umpnpmgr.dll is being loaded at a different base address. In Spanish
systems this base address is 0x76770000 but current exploits are
assumming (I guess) 0x767a0000. Then I did a quick hack to HOD's exploit
and it worked perfectly. I also modified Metasploit's module and
included a target for Spanish systems. I've attached resulting exploits
(they are trivial, though).

Is it usual that Windows DLLs have different base address across same
Windows/SP versions (but different languages)?
