Multiple Vulnerabilities in Microsoft Edge (Chromium-based) – Take Action Now

Recently, CERT-In issued a noteworthy Vulnerability Note, CIVN-2024-0154, highlighting multiple vulnerabilities in Microsoft Edge (Chromium-based) browsers. These vulnerabilities pose a significant risk, potentially allowing attackers to access sensitive information and execute arbitrary code on affected systems. This blog serves as a comprehensive overview of the situation and offers actionable insights to mitigate the risks.

Understanding the Vulnerabilities:

The vulnerabilities identified in Microsoft Edge (Chromium-based) stem from various sources, including “Use after free in Dawn,” “Out of bounds read in V8 API,” and “Type Confusion in ANGLE.” Exploitation of these vulnerabilities could occur through specially crafted requests sent to targeted systems. The consequences of successful exploitation are severe, ranging from unauthorized access to sensitive data to the execution of arbitrary code, thereby compromising system integrity and user privacy.

Impact and Severity:

Given the severity rating of HIGH assigned by CERT-In, it’s imperative for users to grasp the potential impact of these vulnerabilities. Systems running Microsoft Edge versions prior to 124.0.2478.67 are particularly vulnerable. The exploitation of these vulnerabilities could lead to data breaches, system compromise, and unauthorized access, posing significant risks to individuals and organizations alike.

Recommended Actions:

To mitigate the risks associated with these vulnerabilities, immediate action is necessary. CERT-In advises users to:

1. Update Microsoft Edge:

Ensure that your Microsoft Edge browser is updated to version 124.0.2478.67 or later. Regularly check for updates and install them promptly to safeguard against known vulnerabilities.

2. Exercise Caution:

Until the update is applied, exercise caution while browsing the internet. Avoid clicking on suspicious links, downloading files from unknown sources, and visiting potentially malicious websites.

Stay Informed, Stay Secure:

Cyber threats are persistent and evolving, but with vigilance and proactive measures, individuals and organizations can bolster their defenses. Stay informed about cybersecurity advisories, follow best practices for online security, and prioritize the protection of your digital assets.

The vulnerabilities identified in Microsoft Edge (Chromium-based) browsers underscore the importance of proactive cybersecurity measures. By staying informed, updating software promptly, and exercising caution online, users can mitigate the risks posed by potential threats. Remember, cybersecurity is a shared responsibility, and together, we can navigate the digital landscape securely.

Stay protected, stay vigilant.
