CVE-2022-3054 is a vulnerability identified in Google Chrome versions prior to 105.0.5195.52, involving insufficient policy enforcement within the DevTools component. Specifically, this flaw allows a remote attacker to potentially trigger heap corruption by crafting a malicious HTML page. Heap corruption vulnerabilities can lead to unpredictable behavior, including crashes or arbitrary code execution, depending on how the corrupted memory is leveraged. The vulnerability does not require any privileges or prior authentication (AV:N/PR:N), but does require user interaction (UI:R), meaning the victim must visit or interact with a maliciously crafted webpage. The vulnerability impacts the integrity of the system (I:H) but does not directly affect confidentiality or availability. The CVSS v3.1 base score is 6.5, categorized as medium severity. No known exploits in the wild have been reported to date. The vulnerability arises due to inadequate enforcement of security policies in DevTools, which is a developer feature embedded in Chrome, potentially allowing malicious content to bypass intended restrictions and corrupt heap memory. Since the affected versions are prior to 105.0.5195.52, updating to the patched version or later is critical to mitigate this risk.

For European organizations, this vulnerability poses a moderate risk primarily to end-user systems running outdated versions of Google Chrome. Since Chrome is widely used across Europe in both enterprise and consumer environments, the potential for exploitation exists wherever users might visit malicious or compromised websites. The heap corruption could be exploited to execute arbitrary code or cause browser crashes, potentially leading to further compromise of user systems or disruption of business operations. While the vulnerability does not directly impact confidentiality, successful exploitation could be a stepping stone for attackers to gain further access or execute malicious payloads. Organizations with high reliance on Chrome for web applications, especially those with users who have elevated privileges or access to sensitive data, could face increased risk. Additionally, sectors such as finance, government, and critical infrastructure in Europe, which are frequent targets of cyberattacks, may be more concerned about such vulnerabilities. However, the requirement for user interaction and the absence of known active exploits somewhat limit immediate risk.

1. Immediate patching: Ensure all Chrome installations are updated to version 105.0.5195.52 or later, as this version contains the fix for CVE-2022-3054. 2. Browser policy enforcement: For enterprise environments, use centralized management tools (e.g., Google Admin Console or Group Policy) to enforce automatic updates and restrict installation of outdated Chrome versions. 3. User awareness: Educate users about the risks of interacting with untrusted websites and the importance of keeping browsers updated. 4. Network controls: Implement web filtering and threat intelligence-based URL blocking to reduce exposure to malicious websites that could exploit this vulnerability. 5. Monitoring and detection: Deploy endpoint detection and response (EDR) solutions to monitor for unusual browser behavior or crashes that might indicate exploitation attempts. 6. Limit DevTools access: Where possible, restrict or disable DevTools usage in managed environments to reduce the attack surface related to this vulnerability. 7. Incident response readiness: Prepare to respond to potential exploitation attempts by having updated incident response plans and forensic capabilities focused on browser-based attacks.
