CVE-2022-41035: Medium Vulnerability in Microsoft Edge Chromium

CVE-2022-41035 is a medium-severity spoofing vulnerability affecting Microsoft Edge (Chromium-based). This vulnerability allows attackers to manipulate the browser's behavior, potentially leading to unauthorized actions. With a CVSS score of 5.3, it poses a moderate risk to organizations utilizing this browser.

Risk to organizations includes potential integrity breaches, as the vulnerability can be exploited with user interaction. Attackers may leverage this flaw to perform unauthorized actions within the browser, which could compromise sensitive information.

Organizations should prioritize patching immediately. Users are required to interact with the browser, meaning that social engineering tactics could be employed to exploit this vulnerability.

The vulnerability was published on October 11, 2022, and has since been modified. As of now, there are no known public exploits or proofs of concept available.

Vulnerability Details

The official description of CVE-2022-41035 states that it is a spoofing vulnerability in Microsoft Edge (Chromium-based). It is classified under CWE-362, which is associated with race conditions. This vulnerability allows attackers to manipulate user actions through a crafted web page, hence posing a risk to user integrity.

The CVSS score of 5.3 indicates a medium severity level, with the following attributes: Attack Vector: NETWORK, Attack Complexity: HIGH, Privileges Required: NONE, User Interaction: REQUIRED, Confidentiality Impact: NONE, Integrity Impact: HIGH, and Availability Impact: NONE.

The affected product is Microsoft Edge (Chromium-based), specifically all versions prior to 106.0.1370.34.

Technical Analysis

The root cause of CVE-2022-41035 is a flaw in the handling of user interactions, which allows an attacker to manipulate the browser's behavior when a user engages with a malicious web page. The attack vector is network-based, meaning that the attacker can exploit this vulnerability remotely.

The attack complexity is high, as it requires specific conditions to be met, including user interaction. Consequently, the attacker must entice the user to visit the malicious site. No privileges are required to exploit this vulnerability, and user interaction is necessary for successful exploitation.

Regarding impact, if successfully exploited, the integrity of the system could be compromised, leading to unauthorized actions on behalf of the user. However, the confidentiality and availability aspects are not affected.

Risk & Impact Analysis

The real-world risk associated with CVE-2022-41035 is significant, especially for organizations that rely on Microsoft Edge for day-to-day operations. The potential for integrity breaches means that sensitive data could be manipulated or accessed without appropriate authorization.

Organizations that have deployed Microsoft Edge should assess their exposure to this vulnerability and prioritize patching it in their next maintenance cycle. The urgency level is medium, as while exploitation is complex, the consequences can still be severe.

With the possibility of exploitation through social engineering tactics, the blast radius may extend to all users engaging with the browser, potentially leading to a broader impact across the organization.

Exploitation Status

Affected Versions

All versions of Microsoft Edge (Chromium-based) prior to 106.0.1370.34 are affected by this vulnerability.

Mitigation & Remediation

Microsoft has provided a patch for this vulnerability. Organizations should update Microsoft Edge to version 106.0.1370.34 or later to mitigate this risk. If immediate patching is not possible, consider implementing network controls to limit exposure to potentially malicious web pages.

Organizations may also consider engaging in penetration testing to assess their security posture against this vulnerability.

Detection Guidance

Organizations should monitor logs for any unusual user interactions, especially on web pages that may be crafted to exploit this vulnerability. Look for behavioral anomalies indicating potential misuse of the browser.

AppSecure Threat Intelligence Insight

CVE-2022-41035 represents a significant risk in the realm of browser security, emphasizing the importance of timely updates and user awareness. As attackers increasingly target user interactions, organizations must remain vigilant.

Security teams should consider regular penetration testing to identify weaknesses and ensure defenses are robust against social engineering attacks.

Engaging in a comprehensive vulnerability management program can provide organizations with the necessary framework to address vulnerabilities proactively.

Additionally, organizations should stay updated on emerging threats and consider adopting cloud penetration testing to safeguard against vulnerabilities that may arise in cloud environments.
