CVE-2022-4195: Medium Vulnerability in Google Chrome

CVE-2022-4195 is a medium severity vulnerability affecting Google Chrome versions prior to 108.0.5359.71. This vulnerability allows a remote attacker to bypass Safe Browsing warnings through the use of a malicious file. Given the reliance on Safe Browsing to protect users from phishing and other malicious sites, this flaw poses a significant risk to users and organizations relying on Chrome for secure browsing.

The CVSS score for this vulnerability is 4.3, which classifies it as medium severity. The risk to organizations includes potential exposure to phishing attacks and malware distribution due to the failure of Safe Browsing to alert users. Organizations should prioritize patching this vulnerability to mitigate the associated risks.

As of now, there is no public exploit confirmed for this vulnerability, but its existence highlights the importance of updating to the latest versions of Chrome to ensure users are protected from potential exploitation.

Organizations should prioritize patching immediately to prevent unauthorized access and exploitation risks stemming from this vulnerability.

Vulnerability Details

This vulnerability allows a remote attacker to bypass Safe Browsing warnings via a malicious file. The impact of this vulnerability is primarily on the integrity of the browsing experience, as it undermines the trust users place in Chrome's protective measures.

Identified as CVE-2022-4195, this vulnerability has a CVSS score of 4.3, indicating a medium severity level. The vulnerability is classified under the Network attack vector, with low complexity, meaning that it could be exploited without requiring advanced skills. Importantly, it requires user interaction to execute the attack, which may mitigate the risk somewhat but does not eliminate it.

The affected product is Google Chrome, specifically versions prior to 108.0.5359.71. The vulnerability was published on November 30, 2022.

Technical Analysis

The root cause of CVE-2022-4195 lies in the insufficient policy enforcement within the Safe Browsing feature of Google Chrome. This failure allows attackers to exploit the browser’s functionality by delivering harmful files that can go undetected by the user.

The attack vector is network-based, necessitating that an attacker deliver the malicious file over the internet. The attack complexity is classified as low, indicating that it can be executed without sophisticated techniques. Attackers do not need special privileges to exploit this vulnerability, but they do require user interaction to trigger the attack.

The impacts on confidentiality, integrity, and availability are varied: confidentiality is not affected, integrity is compromised, and availability remains intact. This means that while the browser remains operational, the integrity of the browsing experience is at risk, making users susceptible to malicious attacks.

Risk & Impact Analysis

The real-world deployment risk of CVE-2022-4195 is significant, especially for organizations that rely heavily on Google Chrome for secure browsing. The potential for attackers to bypass Safe Browsing warnings increases the likelihood of successful phishing attempts and malware infections, thus impacting organizational security.

Given the nature of the vulnerability, organizations should assess their risk posture and prioritize remediation efforts accordingly. The urgency for organizations to address this vulnerability is elevated, as it poses a clear threat to user safety and the integrity of data.

Based on CVSS and the KEV data, organizations should prioritize patching immediately to prevent unauthorized access and exploitation risks stemming from this vulnerability.
