Initial Reconnaissance
When delving into Chemistry challenges on HackTheBox, initiating with thorough reconnaissance is crucial. Utilize soft skills like observation and critical thinking. Familiarize yourself with the HTB Academy modules, especially on privilege escalation. Analyze the challenge context and goals efficiently. Understand the significance of initial data gathering for further progress. This initial phase sets the tone for successful navigation through the chemistry challenges, enhancing your cyber expertise.
NMAP
Let’s perform an NMap Scan on the machine for open ports and services
Visiting on port 5000 reveals the presence of a CIF Analyzer operating on that port, which constitutes a specialized tool intended for the analysis of CIF (Crystallographic Information Files) files utilized across a variety of applications. This analytical tool appears to provide functionalities that facilitate the evaluation of data integrity and quality, thereby assisting users in deriving significant insights into their workflows. Upon further exploration, one may observe that the CIF Analyzer features a user-friendly interface, which enables straightforward navigation and interaction, thus making it accessible to both technical and non-technical users.
Let’s try signing up (registering) here.
Then we see an upload functionality that requires a valid CIF file. At this point, I had no idea what a CIF file was, so I turned to Google to gather some information about it. After some research, I discovered that CIF stands for Crystallographic Information Files, which is often used in various applications for data representation. Intrigued by this, I decided to delve deeper to understand its structure and potential exploits better. My curiosity led me to explore ways to manipulate this file type, as I was particularly interested in vulnerability assessments. I started learning techniques to abuse the functionality surrounding the CIF file upload, hoping to uncover any security flaws that could potentially allow me to achieve Remote Code Execution (RCE) and ultimately obtain a reverse shell. To aid my understanding of the CIF format, I downloaded an example.cif file, analyzing its contents to discern how it operates and to identify any weaknesses that I could exploit in further testing.
The contents of the example.cif file doesn’t give me anything useful in particular.
Identifying the First Set of Clues
As you delve deeper into the Chemistry challenges on HackTheBox, honing your skills in identification becomes crucial. The second step involves keenly spotting the initial clues presented before you. Utilize your soft skills to decipher hidden patterns and connections. Familiarize yourself with the cookie policy of the platform to navigate efficiently. This phase marks a significant leap in your understanding of cyber challenges. Embrace this opportunity to enhance your proficiency in hack methodologies.
Let’s see if there are CVEs on this CIF by searching on Google.
Found some vulnerabilities but nothing useful in particular.
Then I turned to the official discussion for this machine on HTB. After conducting extensive research, I uncovered valuable information regarding exploitation tactics. This journey led me to two very informative links that delve into the details of an important vulnerability. The first link provides insights on CVE-2024-23346, which describes an arbitrary code execution vulnerability in Pymatgen due to insecure handling. This source is particularly useful for anyone looking to understand the implications of the vulnerability and how it can be exploited in practical scenarios.
Moreover, I also found crucial information on the official advisory from GitHub, available at this link, which outlines the security issues and provides context on the versions affected. The advisory offers a comprehensive view of how this vulnerability arose, the impact it could have, and the best practices to mitigate any associated risks.
Using the knowledge gathered from these sources, I proceeded to craft a payload that exploits this specific vulnerability. This payload is designed to demonstrate the exploit’s effectiveness in a controlled environment, allowing for a better understanding of the underlying mechanics.
The above code contains a CIF (Crystallographic Information File) structure description, but with an embedded command attempting to exploit Python’s attribute resolution to create a reverse shell.
Upload the malicious CIF file to the designated portal, and once the upload is successful, the view button will appear prominently on your screen.
Triggering the Reverse Shell
- The modified payload was uploaded to the website.
- By clicking the “View” button on the website, the payload was executed on the server, resulting in a reverse shell connection back to the attacker’s machine.
The reverse shell provided interactive access to the target system’s shell.
Enumerating the File System
With shell access in hand, standard enumeration commands (e.g., ls -la, find / -type f) were used to map the system. A directory named instance was discovered containing a SQLite database file, database.db.
Accessing the SQLite Database
Using the sqlite3 tool, the database was queried:
sqlite3 instance/database.dbA query to list user data revealed stored usernames and MD5-hashed passwords.
Cracking the MD5 Hash
- The MD5 hash for the user “rosa” was extracted.
- The hash was submitted to CrackStation, an online cracking tool, to retrieve the plaintext password.
With the credentials for “rosa” now in hand, the next step was to gain further access via SSH.
SSH Connection
Using the obtained credentials for user “rosa”, an SSH session was initiated:
ssh rosa@10.10.11.38The connection was successful and access to the user account was established. The user flag was located within the user’s home directory.
Service Discovery on Port 8080
Further reconnaissance identified another service running on port 8080. Analysis of the service banner revealed that it was running aiohttp/3.9.1, a popular asynchronous HTTP framework for Python.
CVE-2024-23334: Local File Inclusion (LFI) & Path Traversal
- Vulnerability Details:
The vulnerability (CVE-2024-23334) is a Local File Inclusion (LFI) and path traversal issue in the aiohttp library. It arises due to insufficient sanitization when handling static file requests. Attackers can traverse the directory structure to access sensitive files.
Exploiting the LFI
- A curl command was crafted to exploit the vulnerability. By carefully manipulating the file path in the request, it was possible to traverse directories and access files that should not have been exposed.
- The crafted request successfully retrieved the root flag by exploiting the LFI vulnerability.
Example exploitation command (simplified):
curl http://10.10.11.38:8080/../../../../etc/passwd(Note: The actual payload was tailored to retrieve the root flag.)
