Exploitation Summary
EIP tracks 1 public exploit for CVE-2024-56433. PoCs published by JonnyWhatshisface.
AI-analyzed exploit summary This repository contains a proof-of-concept exploit for CVE-2024-56433, which leverages insecure default subordinate ID assignment in shadow-utils to allow local users to impersonate other users by changing their UID/GID within their assigned range. The PoC includes both C and Python implementations to demonstrate the vulnerability.
Description
shadow-utils (aka shadow) 4.4 through 4.17.0 establishes a default /etc/subuid behavior (e.g., uid 100000 through 165535 for the first user account) that can realistically conflict with the uids of users defined on locally administered networks, potentially leading to account takeover, e.g., by leveraging newuidmap for access to an NFS home directory (or same-host resources in the case of remote logins by these local network users). NOTE: it may also be argued that system administrators should not have assigned uids, within local networks, that are within the range that can occur in /etc/subuid.
