What is CVE-2024-0519?

CVE-2024-0519 is a high-severity security vulnerability found in Google Chrome, specifically within the V8 JavaScript engine. As a widely used web browser, Google Chrome serves millions of users and organizations by providing a platform for web applications, browsing, and online communication. This vulnerability allows remote attackers to exploit out-of-bounds memory access, potentially leading to heap corruption through maliciously crafted HTML content. If successfully exploited, organizations risk exposing sensitive information, compromising user interactions, and introducing additional security threats to their systems.

Technical Details

The vulnerability arises from improper handling of memory access operations within the V8 engine, which is responsible for executing JavaScript code within Chrome. Specifically, an attacker can craft a web page that triggers this out-of-bounds access, leading to unpredictable behavior within the browser. This kind of vulnerability can allow attackers to gain control over the affected system, manipulate web processes, or inject harmful code that executes under the user’s session context.

Impact of the Vulnerability

Heap Corruption: The nature of the vulnerability allows attackers to corrupt the memory heap, which can cause the browser to behave erratically or crash. This could be exploited to execute arbitrary code, leading to unauthorized control over the victim's system.
Data Breach Risks: By successfully exploiting this vulnerability, attackers may gain access to sensitive user data or authentication tokens stored within the browser, potentially enabling further attacks or data theft.
Increased Attack Surface: As Chrome is widely adopted, the presence of this vulnerability can serve as a gateway for attackers to compromise not only individual users but also enterprises, allowing broader lateral movement within organizational networks, especially if exploited in conjunction with other vulnerabilities.

CISA Reported

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace

The CISA's recommendation is: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
