****Introduction****

This is a **Messaging Web Application** in **PHP** and **MySQL Database**. This project is a web-based messaging or chat platform where users can communicate with each other online. This project has multiple features that automatically load messages or chat updates. With the help of JavaScript, Ajax, and jQuery, users can have a better experience while using the application. The purpose of this project is to share this with the IT/CS students to have an idea of how does this kind of application was developed.

****About the Messaging Web Application****

I developed this project using the following:

*   **XAMPP v3.3.0** as my local webserver that has a **PHP Version 8.0.7**
*   **PHP Language**
*   **MySQL Database**
*   **HTML**
*   **CSS**
*   **JavaScript**
*   **jQuery**
*   **Ajax**
*   **Bootstrap**

The project can be accessed by registered users only which means user registration is a must for using this web application. The system will require the users some personal information including their desired avatar. Talking about the functionalities, the user can view all the conversations of him/her with the other user. by default, the conversation box will only load 25 latest messages of both users and to load the previous messages, users must scroll to the oldest message shown to trigger the system to another 25 old messages. The sender can delete the message they sent but both users can see if the sender of the message deleted the message. The deleted message will not be totally deleted but it will only be shown a deleted message as the message content on the conversation box instead. The application also has an unread messages count for each conversion. The system does not require approval in order for users to send a message to others. The logged-in users can also view the other users' profile information.

****Features****

*   **Secure Login and Registration**
*   **View Personal Profile**
*   **View Other Users Profile**
*   **Search User by Name and Email**
*   **List all Users that been Communicated With**
    *   **Each item shows the user's name, email, and the last message**
    *   **Shows an Unread Messages Count Badge Beside the User Avatar**
    *   **Automatically updates unread messages count and the last message sent**
    *   **Automatically Re-orders the list from latest to oldest**
*   **Conversation Box**
    *   **Display 25 messages by default**
    *   **Loads another 25 old messages when scrolling to the top**
    *   **Automatically updates new messages without reloading**
    *   **Shows "New Message" Button when a new message has been received and if not at the bottom of the convo box**
    *   **Delete Sent Message**
    *   **Shows Deleted Text for Messages that have been deleted**
    *   **Automatically Change Deleted Message Content to Deleted text when sender deleted his/her sent message**
    *   **"User Icon" serve as the button to redirects to the user profile**
    *   **"Close/Times Icon" to close the conversation.**
*   **Manage Account Details/Credentials**
*   **Logout**

CVE-2022-1347: added sanitizeUserString and sanitizeEmail functions · causefx/Organizr@a09d834

Stored XSS viva .svg file upload in GitHub repository causefx/organizr prior to 2.1.1810. This allows attackers to execute malicious scripts in the user's browser and it can lead to session hijacking, sensitive data exposure, and worse.

**Description**

The application allows .svg files to upload which leads to stored XSS

**Proof of Concept**

1.Download the payload from this link:- https://drive.google.com/file/d/1c1BP5bxXBxtwLfRJTrEPgMWK1yVFDF2R/view?usp=sharing

2.Login to the application with Co-admin account and go to "Settings" -> "Image Manager" and upload the downloaded "XSS.svg" payload.

3.Then login with admin account and go to "Settings" -> "Image Manager" and select the "XSS.svg" and open it on a new tab or open the uploaded location you will see that XSS will trigger and this can lead to the admin account takeover.

**PoC video:**

**Impact**

This allows attackers to execute malicious scripts in the user's browser and it can lead to session hijacking, sensitive data exposure, and worse.

CVE-2022-1345: Stored XSS viva .svg file upload in organizr

Multiple Stored XSS in GitHub repository causefx/organizr prior to 2.1.1810. This allows attackers to execute malicious scripts in the user's browser and it can lead to session hijacking, sensitive data exposure, and worse.

**Description**

The organizr application allows malicious javascript payload in multiple-input fields like "Categories", "Bookmark Tabs" and "Bookmark Categories" for which attacker can takeover the admin account.

**Proof of Concept**

1.Login to the co-admin account and go to go to "Settings" -> "Tab Editor".

2.Now in "Categories", "Bookmark Tabs" and "Bookmark Categories" Add options insert the below payloads:

          <img src=x onerror=alert(document.cookie)>
    
          <img src=x onerror=alert(document.domain)>
    
          <img src=x onerror=alert(document.location)>
    

3.Then login with the admin account and go to "Settings" -> "Tab Editor" and visit the "Categories", "Bookmark Tabs" and "Bookmark Categories" and you will see XSS will trigger in all those fields.

**PoC Video**

**Impact**

This allows attackers to execute malicious scripts in the user's browser and it can lead to session hijacking, sensitive data exposure, and worse.

CVE-2022-1346: Multiple Stored XSS in organizr

Stored XSS due to no sanitization in the filename in GitHub repository causefx/organizr prior to 2.1.1810. This allows attackers to execute malicious scripts in the user's browser and it can lead to session hijacking, sensitive data exposure, and worse.

**Description**

The organizr application doesn't sanitize malicious javascript payload which leads to stored XSS and can also perform to the takeover admin account.

**Proof of Concept**

1.Login with Co-admin account and go to "Settings" -> "Image Manager" and upload any small size jpeg image and intercept the request on burp suite.

2.Then change the name of the uploaded image with the below XSS payload and forward the request:

         <img src=1 onerror=alert(1337)>.jpeg
    

3.Then login with admin account and go to "Settings" -> "Image Manager" and open the uploaded image by Co-admin you will see that XSS will trigger.
