vulnerability analysis and mitigation

CVE-2021-38018 is a security vulnerability discovered in Google Chrome versions prior to 96.0.4664.45. The vulnerability stems from an inappropriate implementation in navigation functionality that allowed remote attackers to perform domain spoofing via a crafted HTML page (NVD, Chrome Release).

The vulnerability has been assigned a CVSS v3.1 Base Score of 6.5 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N. This indicates that the vulnerability can be exploited remotely, requires low attack complexity, needs no privileges, but does require user interaction. The impact primarily affects integrity with no impact on confidentiality or availability (NVD).

If successfully exploited, this vulnerability allows an attacker to perform domain spoofing attacks through crafted HTML pages, potentially misleading users about the authenticity of websites they visit. This could lead to phishing attacks or other forms of web-based deception (NVD).

The vulnerability was patched in Google Chrome version 96.0.4664.45. Users and organizations are advised to update to this version or later to mitigate the risk. The fix was also incorporated into various Linux distributions including Debian and Fedora through their respective security updates (Debian Advisory, Fedora Update).
