Loading vulnerability…
In SMU versions prior to 14.8.7825.01, authenticated users with Storage administrative roles can exploit a flaw in URL handling to access HNAS configuration backup and diagnostic data. This data is normally restricted from users in this role, but improper access control allows them to retrieve sensitive information by manipulating URLs.

This repository provides a proof-of-concept (PoC) exploit for CVE-2023-5808, an Insecure Direct Object Reference (IDOR) vulnerability in Hitachi NAS (HNAS) System Management Unit (SMU) versions prior to 14.8.7825.01. The exploit is implemented in a single Python script (CVE-2023-5808.py), which, when provided with a target host and valid session cookies for a non-Read-Only, non-Global Administrator account, sends a crafted GET request to a vulnerable backup download endpoint. If successful, the script downloads an unencrypted ZIP archive containing sensitive configuration data, including password hashes, private keys, and database dumps. The repository also includes a detailed README.md explaining the vulnerability, exploitation steps, and the contents of the backup archive. The LICENSE file contains the GNU GPL v3 license. The exploit is network-based, requires valid credentials, and demonstrates the risk of information disclosure due to improper access controls in the SMU's backup functionality.
