Hack The Box: Certified Machine Walkthrough – Medium Difficulty

Access is gained using Judith Mader’s credentials, allowing enumeration of network resources. CrackMapExec identifies key accounts like management_svc and ca_operator. Privilege escalation is performed using a Shadow Credentials attack with Certipy, taking control of management_svc. With valid credentials, Evil-WinRM establishes a remote session, leading to the user flag.

For root access, the attack exploits Active Directory Certificate Services by modifying ca_operator’s User Principal Name (UPN) to Administrator, enabling a privileged certificate request. A vulnerable ESC9 certificate is issued without linking back to ca_operator, effectively granting Administrator access. The UPN is restored to avoid detection, and authentication via Kerberos retrieves the NT hash of the Administrator account. Full system control is confirmed by obtaining the root flag.

Hack The Box: Chemistry Machine Walkthrough – Easy Difficulty

A vulnerability in **Pymatgen (CVE-2024-23346)** allowed for **Remote Code Execution (RCE)** through a **malicious CIF file**. By injecting code into the **_space_group_magn.transform_BNS_Pp_abc** field and uploading it to the dashboard, nothing happened initially. However, clicking the **View button** triggered execution, leading to a **reverse shell**. With remote access secured, an **SQLite3 database** was explored, revealing **password hashes**, which were cracked to obtain valid credentials and retrieve the **user flag**.

Further exploration uncovered an **aiohttp/3.9.1** service running on **port 8080**, restricting access to the **assets directory** with a **403 Forbidden** response. Leveraging an **LFI attack**, an **SSH key** was extracted, allowing for **privilege escalation** and access to the **root flag**.

This scenario highlights the importance of **sanitizing file uploads, restricting directory access, and keeping dependencies updated** to mitigate security risks.
