Exploitation Summary

EIP tracks 2 public exploits for CVE-2024-3183. PoCs published by Im10n.

AI-analyzed exploit summary The repository provides a detailed technical writeup and proof-of-concept steps for CVE-2024-3183, a FreeIPA kerberoasting vulnerability. It includes instructions for modifying Impacket to exploit the flaw and demonstrates how a low-privileged user can obtain password hashes for offline brute-forcing.

Description

A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client’s session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the user’s password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principal’s password).
