CVE-2023-5854: Use after free in Google Chrome
Use after free in Profiles in Google Chrome prior to 119.0.6045.105 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via specific UI gestures. (Chromium security severity: Medium)
AI Analysis
Technical Summary
CVE-2023-5854 is a use-after-free vulnerability identified in the Profiles component of Google Chrome versions prior to 119.0.6045.105. This vulnerability arises when a remote attacker convinces a user to perform specific user interface (UI) gestures, triggering a heap corruption condition due to improper memory management. Specifically, the flaw is categorized under CWE-416 (Use After Free), where the program continues to use memory after it has been freed, leading to undefined behavior and potential exploitation. The vulnerability allows an attacker to execute arbitrary code or cause a denial of service by corrupting the heap memory. The CVSS v3.1 base score is 8.8, indicating a high severity level. The attack vector is network-based (AV:N), requiring no privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No known exploits are currently reported in the wild, but the potential for exploitation exists given the nature of the vulnerability. The lack of a patch link suggests that the fix is either newly released or pending, emphasizing the need for prompt updates. The vulnerability affects all users running vulnerable Chrome versions, which is significant given Chrome's widespread adoption globally and in Europe. The attack requires social engineering to induce the user to perform specific UI gestures, making user awareness a critical factor in risk mitigation.
Potential Impact
For European organizations, this vulnerability poses a significant risk due to the widespread use of Google Chrome as a primary web browser across enterprises and public sectors. Successful exploitation could lead to remote code execution, allowing attackers to compromise user systems, steal sensitive data, or disrupt operations. Given the high impact on confidentiality, integrity, and availability, critical infrastructure, financial institutions, and government agencies are particularly at risk. The requirement for user interaction means phishing or social engineering campaigns could be leveraged to trigger the exploit, increasing the threat surface. Additionally, the vulnerability could be used as a foothold for lateral movement within corporate networks, escalating the potential damage. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as threat actors often reverse-engineer disclosed vulnerabilities to develop exploits. The impact is exacerbated in environments where Chrome profiles are heavily used for segregating workspaces or managing multiple identities, as the flaw resides in the Profiles component.
Mitigation Recommendations
Immediately update Google Chrome to version 119.0.6045.105 or later, as this version addresses the vulnerability. Implement enterprise-wide browser update policies to ensure timely patch deployment and reduce exposure to known vulnerabilities. Educate users about the risks of interacting with unsolicited or suspicious UI prompts and gestures, emphasizing caution with unknown links or web content. Deploy endpoint protection solutions capable of detecting anomalous behavior indicative of heap corruption or exploitation attempts. Use browser security features such as site isolation and sandboxing to limit the impact of potential exploitation. Monitor network traffic for unusual patterns that may indicate exploitation attempts, especially those involving social engineering vectors. Restrict or control the use of browser profiles where possible to minimize the attack surface related to this component. Coordinate with IT and security teams to conduct simulated phishing exercises focusing on UI interaction risks to raise awareness. Maintain an inventory of Chrome versions deployed across the organization to identify and remediate outdated instances promptly.
