CVE-2022-23261 - Discovering a Tampering Vulnerability in Microsoft Edge (Chromium-based) and How to Protect Yourself

Cybersecurity researchers have recently discovered a new vulnerability in Microsoft Edge (Chromium-based) web browser - assigned the Common Vulnerabilities and Exposures (CVE) identifier CVE-2022-23261. This security issue can potentially allow a skilled attacker to tamper with edge processes and gain unauthorized access to your personal browsing information. In this comprehensive article, we will examine the details of the vulnerability, demonstrate a code snippet of how the exploit might look, and provide links to original sources to help you better understand CVE-2022-23261.

Vulnerability Details

The newly discovered Microsoft Edge (Chromium-based) vulnerability has been classified as a tampering vulnerability. This means that an attacker with knowledge of the vulnerability could potentially tamper with the processes used by the Edge browser, causing unexpected and potentially harmful behavior. The processes in question handle important tasks such as rendering web pages, managing browser extensions, and through them, potentially gain unauthorized access to personal browsing data.

Here's a simple example of how the exploit might look when executed by an attacker

// CVE-2022-23261 - Edge Tampering Vulnerability Exploit
// Note: This is a simplified example for illustrative purposes only

const edgeProcess = require('edge-browser-process'); // Attacker imports edge process

function tamperEdgeProcess() {
  edgeProcess.on('rendering', (event) => {
    // Attacker gains control when rendering happens
    event.stopImmediatePropagation(); // Stop other listeners from handling the event
    event.preventDefault(); // Cancel default behavior of the event

    const maliciousPayload = '...'; // Attacker injects malicious code or payload
    edgeProcess.execute(maliciousPayload); // Execute malicious payload on user's machine
  });

  edgeProcess.startTampering(); // Enable the tampering
}

tamperEdgeProcess();  // Tamper with Edge processes by calling the tamper function
