CVE-2023-4074 is a high-severity vulnerability affecting Google Chrome versions prior to 115.0.5790.170. This vulnerability allows an attacker to exploit heap corruption through a crafted HTML page, potentially compromising the confidentiality, integrity, and availability of affected systems.
The vulnerability has a CVSS score of 8.8, indicating a high severity level. The exploitability of this vulnerability is considered high, with the potential for significant impact on organizations that do not apply the necessary updates.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. The exploit requires user interaction, but once the user visits a malicious page, the attacker may be able to execute code remotely.
Given the potential for exploitation and the high severity rating, it is crucial for organizations to ensure their Chrome installations are updated to the latest versions.
Vulnerability Details
The vulnerability is classified as a use after free in Blink Task Scheduling. It was published on August 3, 2023, and has been categorized under CWE-416.
The affected product is Google Chrome, and the specific version range affected is all versions prior to 115.0.5790.170.
Technical Analysis
The root cause of the vulnerability is a use after free condition in the Blink task scheduling component of Google Chrome. This situation arises when an object is accessed after it has been freed, leading to potential heap corruption.
The attack vector is network-based, requiring low attack complexity. The attack does not require any privileges, but it does necessitate user interaction, as users must visit a crafted HTML page for the exploit to succeed.
The impacts of this vulnerability are significant, with high confidentiality, integrity, and availability impacts.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data, potential system compromise, and loss of availability due to the exploitation of this vulnerability. The vulnerability's high CVSS score indicates that it poses a serious risk to security.
Organizations should assess their exposure to this vulnerability and prioritize remediation efforts. The urgency is underscored by the ease of exploitation and the requirement for user interaction, which could lead to widespread impact if left unaddressed.
Given the potential for exploitation, organizations should also monitor for any anomalous behavior that could indicate attempts to exploit this vulnerability.
