Hi Roman, I assure you that the address is also different for the French language. With the similar review with ollydbg, the base address for me is 0x76740000. I've attached the resulting exploit and Metasploit's module for french's system.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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)? - -- Cheers, - -Roman PGP Fingerprint: 09BB EFCD 21ED 4E79 25FB 29E1 E47F 8A7D EAD5 6742 [Key ID: 0xEAD56742.
