CVE-2024-20675: Microsoft Edge (Chromium-based) Security Feature Bypass Vulnerability

Microsoft Edge, based on Chromium's open source project, has become increasingly popular among internet users in recent years. It offers a plethora of advanced features, a user-friendly interface, and high-speed browsing capabilities. However, even the most cutting-edge software is not immune to security vulnerabilities. Today, we'll be discussing CVE-2024-20675, a security feature bypass vulnerability in Microsoft Edge that could potentially compromise user data and system security.

Exploit details

To exploit this vulnerability successfully, an attacker must entice a user into visiting a specially crafted or compromised webpage via targeted emails or other communication methods. Once the user accesses the malicious website, the attacker will proceed to bypass the security feature within Microsoft Edge, opening the door for data theft and other illicit activities.

The vulnerability stems from a lack of proper validation of user-supplied data before it is processed. Consequently, an attacker can execute arbitrary code on the user's machine by manipulating specific input parameters.

Here is a code snippet that demonstrates how a potential attacker might exploit the vulnerability

// Code snippet for CVE-2024-20675
// A malicious website injects code to bypass Edge's security feature and execute arbitrary code

function exploit(user_data) {
    let payload = 'arbitrary_code_to_be_executed';
    let edge_security_feature = 'specific_security_feature';

    // Bypass security feature
    let bypass = bypassEdgeSecurityFeature(edge_security_feature);
    if (bypass) {
        // Execute arbitrary code
        let exec = executeArbitraryCode(payload);
        if (!exec) {
            console.error('CVE-2024-20675 exploit failed.');
        } else {
            console.log('CVE-2024-20675 exploit successful.');
        }
    } else {
        console.error('Cannot bypass Edge security feature.');
    }
}

function bypassEdgeSecurityFeature(feature) {
    // Sample logic to bypass the security feature
    return feature == 'specific_security_feature' ? true : false;
}

function executeArbitraryCode(code) {
    // Sample logic for executing arbitrary code
    let result = eval(code);
    return result;
}

// Inject exploit code into a user's browser
let user_data = getUserData();
exploit(user_data);

To protect against this vulnerability, Microsoft has released a security update that patches the underlying issue. You can find more details about the update and the affected Microsoft Edge versions in the Microsoft Security Response Center.

Conclusion

CVE-2024-20675 exposes Microsoft Edge to a security feature bypass vulnerability that could be hazardous to sensitive information and overall system security. It is highly recommended to apply the available patch immediately and remain vigilant when visiting unfamiliar websites or clicking on suspicious links.
