Google, in light of recent events, has launched a critical update for a high-severity Chrome zero-day vulnerability.
As per recent reports, Google claims that the vulnerability has been actively exploited.
It's worth noting that the vulnerability pertains to the WebRTC framework and, when exploited, can lead to program crashes or arbitrary code execution.
In this article, we'll dive into details of the vulnerability and the countermeasures Google has implemented to keep the vulnerability from being exploited further.
As of now, Clément Lecigne and Vlad Stolyarov of Google's Threat Analysis Group are the two personnel credited with discovering the vulnerability.
Details of any other security defects resulting in Google Chrome exploits have not been released till now, as it prevents further exploits.
The Chrome zero-day vulnerability, identified as CVE-2023-7024, is being described as a heap-based buffer overflow bug in the WebRTC framework.
It's worth mentioning that such browser vulnerabilities raise significant concerns pertaining to online security risks.
Such circumstances make exploiting the Chrome zero-day vulnerability a feasible option for threat actors, as it can be used to expand the attack surface once initial access has been acquired.
In addition to retaining information, Google has released a patch to keep such browser vulnerabilities from being exploited.
Given the potential impacts of the Chrome zero-day vulnerability, users are urged to adhere to web security best practices and update their Chrome browsers.
Taking a look back at 2023, it's worth mentioning that CVE-2023-7024 has now become the eighth vulnerability Google has patched over during 2023.
CVE-2023-2033 - a type confusion vulnerability in the V8 JavaScript engine that allowed threat actors to exploit heap corruption using a crafted HTML page.
CVE-2023-2136 - an integer overflow vulnerability in Skia that compromised the renderer process and enabled a threat actor to perform a sandbox escape.
CVE-2023-3079 - another type confusion vulnerability with similar outcomes as its predecessor.
CVE-2023-4762 - a type confusion vulnerability in the V8 JavaScript engine and to the execution of arbitrary code by a threat actor.
CVE-2023-6345 - an integer overflow in bug Skia that was exploited by threat actors in the wild.
Given that Google Chrome is widely used across multiple platforms, vulnerabilities within the browser serve as a feasible option for threat actors with malicious intent.
The most recent Chrome zero-day vulnerability, if exploited, is similar to some of its predecessors and can lead to program crashes or arbitrary code execution.
The initial access acquired by exploiting the vulnerability could then be used to expand the attack surface and maximize damage to the target system.
