Exploitation Summary

EIP tracks 1 public exploit for CVE-2005-0045. PoCs published by cybertronic.

AI-analyzed exploit summary This exploit targets CVE-2005-0045, a vulnerability in the Windows SMB client (MRXSMB.SYS) that allows a malicious SMB server to trigger a buffer overflow via crafted Transaction response packets, leading to a denial-of-service (BSOD) or potential code execution on Windows 2000 systems.

Description

The Server Message Block (SMB) implementation for Windows NT 4.0, 2000, XP, and Server 2003 does not properly validate certain SMB packets, which allows remote attackers to execute arbitrary code via Transaction responses containing (1) Trans or (2) Trans2 commands, aka the "Server Message Block Vulnerability," and as demonstrated using Trans2 FIND_FIRST2 responses with large file name length fields.
