Project 3 Privilege Escalation 2in This Project You Are Assigned To

This project involves performing privilege escalation on a Windows 2008 Server within a Capture-the-Flag (CTF) environment. The task includes discovering and exploiting a vulnerable MS SQL service using the Metasploit Framework to gain unprivileged access, then escalating privileges to achieve a high-privileged shell. The process entails network scanning, password cracking, exploiting SQL procedures, and privilege escalation exploits, culminating in a security breach simulation. The entire procedure is to be performed from Kali Linux, adhering to specific commands and steps as outlined.

The aim of this project is to simulate a malicious attack on a Windows 2008 Server to understand vulnerabilities, exploit them, and analyze their impact on information security. This involves multiple stages, starting with network reconnaissance, moving through password cracking, gaining access, escalating privileges, and finally demonstrating the breach's consequences. Each step is designed to highlight specific vulnerabilities and attack vectors that attackers could exploit in real-world scenarios, emphasizing the importance of robust security measures and proactive defenses.

The first stage involves scanning the network to identify open ports corresponding to MS SQL Server, specifically port 1433. Using Nmap from Kali Linux, precise commands are issued to detect active services. For instance, a typical command such as nmap -sV -p 1433 [target IP] can reveal whether the port is open, indicating a potential target for further exploitation. The screenshot of this scan serves as evidence of the vulnerability's presence, which is crucial for advancing the attack vector.

Next, the attacker attempts to crack the password for the 'sa' account, the most privileged SQL server account. This is achieved by utilizing the Metasploit Framework and a password dictionary such as 'rockyou.txt'. The process involves decompressing the wordlist, launching Metasploit, and predefining the relevant modules, specifically the mssql_login module. Commands like search mssql_login and use auxiliary/mssql/mssql_login are employed to set options such as target IP, username, and password file. The brute-force attack aims to discover the 'sa' account password, which, once obtained, becomes a key to further infiltration.

Upon successful password cracking, the attacker proceeds to establish a shell on the Windows 2008 Server. This is performed by exploiting the xp_cmdshell stored procedure, which allows executing operating system commands directly from SQL Server. Using Metasploit payloads such as windows/x64/meterpreter/reverse_tcp, the attacker configures the exploit with the target's IP and port settings, then runs the exploit to gain command-line access. These commands enable interaction between Kali Linux and the target server, ultimately providing a low-privileged shell.

After obtaining a shell, it is important to verify the privilege level. Using commands like whoami, the attacker assesses whether the current shell has low privileges. If so, subsequent steps involve privilege escalation techniques, such as using Metasploit's exploit suggester module. This module scans the system for known vulnerabilities and recommends exploits, such as MS16-014 or other privilege escalation exploits, which can be used to elevate privileges to SYSTEM level. The attacker then executes the chosen exploit on the identified session, configuring necessary options as indicated by the module's output.

Following successful privilege escalation, the attacker verifies the high-privilege status by again running whoami and confirming administrative or SYSTEM-level access. This elevation of privileges demonstrates a breach of the system's confidentiality, integrity, and availability principles, illustrating how vulnerabilities like weak passwords, unpatched systems, and disclosable procedures such as xp_cmdshell can be manipulated maliciously.

The final part of the exercise involves intentionally causing a security breach, such as deleting files, modifying configurations, or stopping services, to simulate the real-world impact of such attacks on organizational security. Documentation with screenshots of each step validates the attack process and underscores the importance of network security practices like patch management, strong password policies, and controlled privilege escalation.

Reflecting on this exercise enriches understanding of the attack lifecycle and the vulnerabilities present in legacy systems like Windows 2008. It highlights the critical need for vulnerability assessments, timely updates, and defensive strategies to mitigate similar real-world threats. Recognizing how tools like Metasploit streamline exploitation processes, attackers can efficiently identify and leverage vulnerabilities, making continuous vulnerability management and defender awareness vital. Questions remain about the most effective countermeasures for legacy systems, emphasizing ongoing research and investment in security infrastructure to prevent such exploits.
