CVE-2022-3842 is classified as a high-severity vulnerability that affects Google Chrome versions prior to 105.0.5195.125. This vulnerability allows for a use after free condition in the Passwords feature. If exploited, it enables a remote attacker, who has compromised the renderer process, to potentially exploit heap corruption via a crafted HTML page. The impact of this vulnerability is significant, as it threatens the confidentiality, integrity, and availability of the affected systems.
The CVSS score for this vulnerability is 7.5, indicating a high level of risk to organizations. The attack vector is through the network, which implies that a successful attack can occur without physical access to the vulnerable system. The complexity of the attack is rated as high, requiring some level of user interaction to exploit the vulnerability effectively.
Given the nature of this vulnerability, organizations using Google Chrome should prioritize patching immediately. Failure to do so could result in unauthorized access and manipulation of sensitive information, leading to severe repercussions for both the organization and its users.
Currently, there are no public exploits confirmed for this vulnerability, but the potential for exploitation exists, making it crucial for organizations to stay vigilant and apply the necessary updates as soon as possible.
Vulnerability Details
The official description from the CVE database states: 'Use after free in Passwords in Google Chrome prior to 105.0.5195.125 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page.' This vulnerability is classified under CWE-416: Use After Free.
The attack is characterized by the following metrics: a CVSS score of 7.5, a high attack vector through the network, high attack complexity, no privileges required, and the necessity for user interaction.
Organizations should be aware of the need to update Google Chrome to version 105.0.5195.125 or later to mitigate this vulnerability. The publication date for this vulnerability was January 2, 2023, and it has been marked as modified since its discovery.
Technical Analysis
The root cause of CVE-2022-3842 lies in a use after free vulnerability within the Google Chrome Passwords component. This occurs when the application tries to access memory that has been freed, which can lead to heap corruption. This vulnerability is particularly dangerous as it may allow an attacker to execute arbitrary code, leading to a potential system compromise.
The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it remotely without needing physical access to the victim's device. The complexity of the attack is rated as high, requiring the victim to interact with a malicious web page that triggers the vulnerability.
No privileges are required for an attacker to exploit this vulnerability, which amplifies the risk. User interaction is required, as the victim must navigate to the crafted HTML page to trigger the exploit. The impact of this vulnerability is severe, affecting confidentiality, integrity, and availability.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information, as attackers may exploit this vulnerability to manipulate data or execute arbitrary code. The high severity of the vulnerability, coupled with its remote exploitability, means that organizations must act swiftly to protect their assets.
The blast radius for this vulnerability is considerable, as it affects all users of the impacted versions of Google Chrome. Given the widespread use of this browser, the potential for large-scale exploitation is significant. Organizations should assess their use of Google Chrome and prioritize remediation efforts.
The urgency for organizations to address this vulnerability is high due to its CVSS score of 7.5. Organizations should prioritize patching immediately to mitigate risks associated with unauthorized access and data manipulation.
