CVE-2024-10231: Google Chrome V8 RCE Vulnerability

CVE-2024-10231 Overview

CVE-2024-10231 is a type confusion vulnerability in the V8 JavaScript engine used by Google Chrome versions prior to 130.0.6723.69. A remote attacker can exploit this flaw to trigger heap corruption by serving a crafted HTML page to a victim. Successful exploitation can lead to arbitrary code execution within the renderer process. Google rated the Chromium security severity as High, and the issue is tracked under CWE-843: Access of Resource Using Incompatible Type. The vulnerability requires user interaction, typically visiting a malicious or compromised web page.

Critical Impact

Remote attackers can corrupt the V8 heap through a crafted HTML page, enabling potential arbitrary code execution in the Chrome renderer process.

Affected Products

• Google Chrome versions prior to 130.0.6723.69 on Desktop
• Chromium-based browsers incorporating vulnerable V8 builds
• Embedded applications using affected V8 engine versions

Discovery Timeline

• 2024-10-22 - CVE-2024-10231 published to NVD following the Chrome Stable channel update

Technical Details for CVE-2024-10231

Vulnerability Analysis

The flaw is a type confusion bug in V8, the JavaScript and WebAssembly engine that powers Chrome. Type confusion occurs when code allocates or accesses a resource using one type and later operates on it as an incompatible type. In V8, this typically arises from incorrect assumptions made by the optimizing compiler (TurboFan or Maglev) about object shapes, element kinds, or map transitions. When the engine treats one object representation as another, internal invariants break, leading to out-of-bounds reads and writes on the V8 heap.

An attacker crafts JavaScript that manipulates object representations to bypass runtime checks. The resulting memory corruption can be shaped into a read/write primitive inside the renderer sandbox. From there, attackers commonly chain a sandbox escape to achieve full code execution on the host.

Root Cause

The root cause is an incorrect type assumption within V8, classified as [CWE-843]. The engine operates on a JavaScript object using a type that differs from its actual underlying representation. This mismatch corrupts adjacent metadata or pointer fields on the heap. Google has not published detailed technical analysis in the public references, and the Chromium Issue Tracker Entry restricts access until the fix is broadly deployed.

Attack Vector

Exploitation occurs over the network and requires user interaction. A victim must load a crafted HTML page containing malicious JavaScript that triggers the type confusion in V8. No authentication or prior access to the target system is required. The vulnerability does not need privileged access to execute. Drive-by download scenarios, malvertising, and phishing links to attacker-controlled domains are the primary delivery methods. Refer to the Google Chrome Update Announcement for vendor details.

No verified public proof-of-concept code is available at the time of writing. The vulnerability mechanism is described in prose only.

Detection Methods for CVE-2024-10231

Indicators of Compromise

• Chrome renderer process crashes with signatures indicating V8 heap corruption or invalid map access
• Unexpected child processes spawned from chrome.exe following web browsing activity
• Outbound connections from Chrome to newly registered or low-reputation domains hosting JavaScript-heavy pages
• Browser telemetry showing prolonged JIT compilation activity tied to specific suspicious URLs

Detection Strategies

• Inventory Chrome installations across the fleet and flag any version below 130.0.6723.69
• Monitor endpoint telemetry for anomalous renderer process behavior, such as unexpected memory allocation patterns or crashes referencing v8::internal
• Correlate browser process anomalies with concurrent network requests to suspicious domains
• Apply web proxy rules to identify HTML responses containing obfuscated JavaScript patterns associated with V8 exploit primitives

Monitoring Recommendations

• Centralize Chrome version reporting through management tooling such as Chrome Browser Cloud Management
• Forward endpoint process and crash telemetry to a SIEM for correlation against threat intelligence feeds
• Track outbound traffic from browser processes for connections to known exploit kit infrastructure

How to Mitigate CVE-2024-10231

Immediate Actions Required

• Update Google Chrome to version 130.0.6723.69 or later on all Windows, macOS, and Linux endpoints immediately
• Restart Chrome after the update to ensure the patched V8 binary is loaded into memory
• Audit Chromium-based browsers and embedded applications for vulnerable V8 builds and apply vendor updates
• Block known malicious domains at the web proxy or DNS layer to reduce drive-by exposure

Patch Information

Google released the fix in the Chrome Stable channel as version 130.0.6723.69 for Linux and 130.0.6723.69/.70 for Windows and macOS. Details are available in the Google Chrome Update Announcement. Administrators should verify automatic updates are enabled and confirm deployment through enterprise management consoles.

Workarounds

• No vendor-supplied workaround exists; patching is the only complete remediation
• Restrict JavaScript execution on untrusted sites using enterprise browser policies as a temporary risk reduction
• Enforce least privilege on endpoints to limit post-exploitation impact if a renderer compromise occurs
• Use network filtering to block access to known malicious or newly registered domains

# Verify Chrome version on Linux/macOS endpoints
google-chrome --version

# Force update check via command line (Windows PowerShell example)
Start-Process "C:\Program Files\Google\Chrome\Application\chrome.exe" -ArgumentList "--check-for-update-interval=1"
