CVE-2022-3305: Use after free in Google Chrome
Use after free in survey in Google Chrome on ChromeOS prior to 106.0.5249.62 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
CVE-2022-3305 is a high-severity use-after-free vulnerability identified in the Google Chrome browser specifically affecting ChromeOS versions prior to 106.0.5249.62. The vulnerability arises from improper memory management in the 'survey' component of Chrome, where a use-after-free condition allows a remote attacker to exploit heap corruption by crafting a malicious HTML page. This type of vulnerability (CWE-416) occurs when a program continues to use a pointer after the memory it points to has been freed, leading to undefined behavior including potential arbitrary code execution. The vulnerability can be triggered remotely without requiring any privileges or authentication, but it does require user interaction, such as visiting a malicious website. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, no privileges required, and user interaction needed. Although no known exploits in the wild have been reported at the time of publication, the severity and nature of the flaw make it a critical concern for users of Chrome on ChromeOS. The lack of a patch link in the provided data suggests that users should verify that their ChromeOS devices are updated to versions 106.0.5249.62 or later to mitigate this vulnerability.
Potential Impact
For European organizations, this vulnerability poses a significant risk due to the widespread use of Google Chrome, including on ChromeOS devices in enterprise and public sector environments. Exploitation could lead to unauthorized code execution, enabling attackers to gain control over affected systems, steal sensitive data, or disrupt operations. Given the high confidentiality, integrity, and availability impact, successful exploitation could result in data breaches, espionage, or service outages. Organizations relying on ChromeOS devices for secure browsing or kiosk applications are particularly vulnerable. The requirement for user interaction means phishing or social engineering campaigns could be used to lure users to malicious sites. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits rapidly after disclosure. The impact is compounded in sectors with strict data protection regulations such as GDPR, where breaches can lead to severe legal and financial consequences.
Mitigation Recommendations
European organizations should ensure all ChromeOS devices are updated to version 106.0.5249.62 or later as soon as possible. Since no patch links were provided, organizations should rely on official Google ChromeOS update channels to obtain the fix. Additionally, organizations should implement network-level protections such as web filtering to block access to known malicious sites and employ endpoint security solutions capable of detecting anomalous behavior indicative of exploitation attempts. User awareness training should emphasize caution when clicking on links or visiting unfamiliar websites to reduce the risk of user interaction-based attacks. Monitoring browser behavior and logs for unusual activity can help in early detection of exploitation attempts. Organizations should also consider restricting the use of ChromeOS devices to trusted networks and environments where possible, and employ application sandboxing and least privilege principles to limit the impact of potential compromises.
