With a CVSS score of 8.8, this vulnerability presents a significant risk to users and organizations.

Organizations should prioritize patching immediately to protect against potential exploits. The vulnerability was published on April 5, 2022, and has been classified under CWE-416, indicating a use after free weakness. The implications of this vulnerability are serious, as it can lead to unauthorized access and manipulation of sensitive data.

The exploitation status is currently unknown, but organizations are advised to remain vigilant and implement security measures to mitigate risks associated with this vulnerability.

In summary, CVE-2022-0605 is a critical issue that necessitates immediate attention from security teams to safeguard their systems from potential exploitation.

Vulnerability Details

The official description of CVE-2022-0605 states that it involves a use after free issue in the Webstore API in Google Chrome prior to version 98.0.4758.102. The vulnerability is classified as high severity with a CVSS 3.1 score of 8.8, indicating a high potential for exploitation. The attack vector is network-based, and while no privileges are required, it necessitates user interaction to trigger the vulnerability.

Technical Analysis

The root cause of this vulnerability lies in improper memory management, leading to a use after free scenario. Attackers can leverage this vulnerability through network interactions, specifically by convincing users to install malicious extensions. The attack complexity is rated as low, as it primarily relies on user interaction, which is a minimal barrier for exploitation.

This vulnerability has significant impacts on confidentiality, integrity, and availability, all rated as high. If successfully exploited, attackers may gain unauthorized access, manipulate data, or disrupt services.

Risk & Impact Analysis

The deployment risk associated with CVE-2022-0605 is substantial due to the potential for heap corruption, which can lead to severe consequences for affected organizations. Failure to patch this vulnerability can result in a significant blast radius, especially if exploited by attackers targeting vulnerable users. The urgency for remediation is high, given the CVSS score and the likelihood of exploitation through social engineering tactics.

Exploitation Status

Affected Versions

All versions of Google Chrome prior to 98.0.4758.102 are affected. Organizations should ensure that their systems are updated to the latest version to mitigate this vulnerability.

Mitigation & Remediation

To mitigate the risks associated with CVE-2022-0605, organizations should apply the latest patches released by Google. The recommended version to upgrade to is 98.0.4758.102 or later. If immediate patching is not possible, consider implementing additional security measures such as limiting user permissions for browser extensions and monitoring for abnormal behavior in user interactions. For comprehensive security assessments, organizations may consider engaging in application security assessment to identify and remediate vulnerabilities.

Detection Guidance

Organizations should monitor logs for unusual extension installation patterns and user interactions with installed extensions. Look for behavioral anomalies that may indicate exploitation attempts. Additionally, network signatures related to malicious extension communications should be analyzed to detect potential threats.

AppSecure Threat Intelligence Insight
