Loading vulnerability…
SMU versions before 14.8.7825.01 contain an authorization flaw in access to configuration backups. An authenticated user assigned a Storage, Server, or combined Server+Storage administrative role can manipulate a URL to retrieve an SMU configuration backup despite that backup normally being restricted from those roles.

This repository provides a proof-of-concept (PoC) exploit for CVE-2023-6538, an Insecure Direct Object Reference (IDOR) vulnerability in Hitachi NAS System Management Unit (SMU) versions prior to 14.8.7825.01. The repository contains three files: the main exploit script (CVE-2023-6538.py), a README.md with detailed vulnerability and exploitation information, and a LICENSE file. The Python script requires the attacker to supply the target host, valid JSESSIONID and JSESSIONIDSSO cookies, and a server ID. It then sends an authenticated GET request to a specific SMU endpoint to download a configuration backup archive (registry_data.tgz). This archive may contain sensitive files, including /etc/shadow from the managed server, leading to potential credential compromise. The exploit demonstrates the ability to enumerate and download configuration data for different servers by manipulating the serverid parameter. The attack vector is network-based, requiring access to the SMU's web interface over HTTPS. The exploit is a PoC and does not provide post-exploitation payloads beyond the file download.
