The vulnerability identified as CVE-2021-37964 affects Google Chrome on ChromeOS versions prior to 94.0.4606.54. This vulnerability allows an attacker with a rogue wireless access point to potentially carry out a wifi impersonation attack via a crafted ONC file. This situation presents a low-severity risk, classified with a CVSS score of 3.3, which underlines the importance of addressing it promptly due to its capability for exploitation in local environments.
Risk to organizations includes unauthorized network access and potential data interception, particularly in environments where users may connect to untrusted wireless networks. Given that exploitation requires user interaction, the attack vector is somewhat limited; however, the existence of this vulnerability highlights the ongoing need for robust network security measures.
Organizations should address this vulnerability in their patch management processes to mitigate any potential risks associated with wifi impersonation. Immediate patching is crucial, especially for users of affected Google Chrome versions.
This vulnerability is currently not actively exploited in the wild, but organizations should still prioritize remediation as part of their security posture.
Vulnerability Details
Inappropriate implementation in ChromeOS Networking in Google Chrome on ChromeOS prior to 94.0.4606.54 allowed an attacker with a rogue wireless access point to potentially carry out a wifi impersonation attack via a crafted ONC file.
The CVSS score for this vulnerability is 3.3, indicating a low severity. The vulnerability's attack vector is local, with low complexity and no privileges required. User interaction is necessary for exploitation, meaning a user must connect to the rogue access point for the attack to succeed.
The affected products include Google Chrome, Debian Linux, and Fedora. The vulnerability was published on October 8, 2021.
Technical Analysis
The root cause of this vulnerability lies in the inappropriate implementation of ChromeOS Networking. The attack vector is local, requiring the attacker to be within proximity to the victim's device to exploit the vulnerability. The attack complexity is rated as low, indicating that the attacker can easily execute the attack with minimal skill.
No privileges are required to exploit this vulnerability, but user interaction is necessary, as the victim must connect to a rogue access point. The impact on confidentiality is none, while integrity is rated as low, meaning the attacker could alter some data but not all. There are no impacts on availability.
Risk & Impact Analysis
Organizations must recognize the real-world risk posed by this vulnerability, particularly in environments with less stringent security controls. The blast radius could extend to any user connecting to a rogue access point, which could lead to unauthorized access to sensitive data.
Given the low CVSS score, the urgency to patch is moderate. Organizations should schedule remediation as part of their normal maintenance cycle but should not overlook the potential risks associated with the vulnerability.

Affected Versions
This vulnerability affects all versions of Google Chrome prior to 94.0.4606.54, as well as Debian Linux 10.0 and 11.0, and Fedora versions 33 and 35.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply the latest updates provided by Google, Debian, and Fedora. Regular patching cycles should be implemented to ensure all affected systems are updated promptly. For users unable to patch immediately, consider implementing network controls to restrict access to unauthorized wireless networks.
Organizations may also benefit from continuous security testing to identify potential vulnerabilities in configurations and access controls.
Detection Guidance
Monitoring for unauthorized access attempts and unusual network behavior is crucial in identifying potential exploitation of this vulnerability. Log indicators from networking devices can help detect rogue access points, while behavioral anomalies in network traffic should be investigated.
AppSecure Threat Intelligence Insight
This vulnerability serves as a reminder of the importance of network security in the context of modern computing environments. Organizations must stay vigilant against emerging threats and ensure their infrastructure is resilient to such vulnerabilities. For further insights, organizations can explore topics such as cloud security assessments and penetration testing methodologies to enhance their security measures.
Overall, staying informed about vulnerabilities like CVE-2021-37964 is essential for maintaining a strong security posture.
