CVE-2023-28284: Unraveling the Microsoft Edge (Chromium-based) Security Feature Bypass Vulnerability

Poster -

Cybersecurity researchers have identified a new vulnerability in Microsoft Edge, the Chromium-based browser which can lead to a Security Feature Bypass. This vulnerability has been assigned the CVE ID CVE-2023-28284, and we will discuss the details, potential exploits, and provide an example code snippet in this blog post. We also provide links to original references and further information on how to mitigate this vulnerability.

The Vulnerability

The CVE-2023-28284 vulnerability in Microsoft Edge (Chromium-based) results from a flaw in the security features of the browser. This vulnerability allows an attacker to bypass certain security features and execute arbitrary code on the targeted system, potentially gaining unauthorized access to sensitive data or compromising the system.

Exploit Details

A skilled attacker could exploit this vulnerability by crafting a malicious website or injecting malicious code into a legitimate website that the target user visits. Once a user visits such a website or an application that contains the exploit code, the attacker can bypass the built-in security features of Edge, leading to arbitrary code execution on the user's system.

Generally, this would involve bypassing the Content Security Policy (CSP) or the Same-Origin Policy (SOP) of Microsoft Edge, allowing the attacker to retrieve content from other websites, gain access to the user's cookies, and more.

Code Snippet

Here is a simple code snippet demonstrating the vulnerability in action. Note that this is for educational purposes only and should not be used for malicious activities.

        }

        // Trigger the bypassing of the security feature
        function exploitCVE202328284() {
            // Code to bypass security features and trigger executeMaliciousPayload()
        }

        // Execute the exploit
        exploitCVE202328284();
    </script>
