CVE-2022-3312 is a vulnerability identified in Google Chrome on ChromeOS versions prior to 106.0.5249.62. The issue stems from insufficient validation of untrusted input within the VPN component of Chrome. This flaw allows a local attacker—someone with physical access to the device—to bypass managed device restrictions. Managed device restrictions are typically enforced by enterprise administrators to control device usage, enforce security policies, and limit user capabilities. The vulnerability is classified under CWE-306, which relates to the improper enforcement of security controls. The CVSS v3.1 base score is 4.6 (medium severity), with an attack vector requiring physical access (AV:P), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), high integrity impact (I:H), and no availability impact (A:N). This means an attacker with physical access can manipulate the VPN input validation to circumvent restrictions that would otherwise limit device usage or network access. No known exploits are reported in the wild, and no patches are explicitly linked in the provided data, though presumably, Chrome versions 106.0.5249.62 and later have addressed this issue. The vulnerability is specific to ChromeOS devices running Chrome, affecting environments where device management policies are critical, such as enterprise or educational settings. The lack of confidentiality and availability impact reduces the risk somewhat, but the high integrity impact means attackers can alter system or device state in unauthorized ways, potentially undermining security controls and policy enforcement.

For European organizations, especially those deploying ChromeOS devices under centralized management (e.g., schools, government agencies, and enterprises), this vulnerability poses a risk of policy circumvention if an attacker gains physical access to devices. The ability to bypass managed restrictions can lead to unauthorized software installation, network access, or data manipulation, undermining organizational security policies. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact could allow attackers to alter device configurations or security settings, potentially facilitating further attacks or data leakage. Physical access requirements limit remote exploitation, but in environments with shared or publicly accessible devices, the risk increases. Additionally, organizations relying on ChromeOS for secure endpoint management must consider this vulnerability in their risk assessments and device handling procedures. The medium severity suggests a moderate risk, but the potential for policy bypass in managed environments elevates concern for organizations with strict compliance or regulatory requirements prevalent in Europe, such as GDPR and NIS Directive obligations.

To mitigate this vulnerability, European organizations should ensure all ChromeOS devices are updated to Chrome version 106.0.5249.62 or later, where the issue is resolved. Device management policies should enforce automatic updates and verify patch compliance regularly. Physical security controls must be strengthened to prevent unauthorized access to devices, including secure storage, access logging, and user authentication mechanisms. Organizations should audit device enrollment and management configurations to detect any unauthorized changes potentially resulting from this vulnerability. Additionally, consider implementing endpoint detection and response (EDR) solutions capable of identifying anomalous device behavior indicative of policy bypass attempts. Training and awareness programs for staff handling ChromeOS devices can reduce risks associated with physical access. Finally, organizations should monitor vendor advisories for any further updates or patches related to this vulnerability and apply them promptly.
