CVE-2024-11116 Overview
CVE-2024-11116 is a user interface (UI) spoofing vulnerability in the Blink rendering engine of Google Chrome. The flaw affects Chrome versions prior to 131.0.6778.69 and stems from an inappropriate implementation within Blink. A remote attacker who convinces a user to perform specific UI gestures can spoof browser interface elements through a crafted HTML page. Google's Chromium project rated this issue as Medium severity. The vulnerability is tracked under [CWE-79] (Improper Neutralization of Input During Web Page Generation) in the NVD record.
Critical Impact
Attackers can manipulate browser UI elements to mislead users into trusting malicious content, enabling phishing and social engineering attacks.
Affected Products
- Google Chrome versions prior to 131.0.6778.69
- Chromium-based browsers incorporating vulnerable Blink builds
- Desktop channels across Windows, macOS, and Linux
Discovery Timeline
- 2024-11-12 - CVE-2024-11116 published to NVD following the Chrome Stable channel update
- 2026-06-17 - Last updated in NVD database
Technical Details for CVE-2024-11116
Vulnerability Analysis
The vulnerability resides in Blink, the rendering engine that powers Chrome's web content processing. Blink handles HTML parsing, layout, and UI element rendering within the browser. An inappropriate implementation in this component allows crafted web content to influence how UI elements are drawn or perceived by the user. The result is a UI spoofing condition where attacker-controlled content can mimic or overlay legitimate browser interface components.
The issue requires user interaction. A victim must engage in specific UI gestures for the spoofing to succeed. This user-gesture requirement limits fully automated exploitation but aligns well with phishing workflows where users are guided into performing actions.
Root Cause
The root cause is an inappropriate implementation within Blink's handling of certain UI-related rendering paths. The defect does not corrupt memory or execute arbitrary code. Instead, it permits visual deception by rendering content in a way that misrepresents the browser's true state. Google's public disclosure does not enumerate the specific Blink component or gesture sequence involved. Additional context is available in the Chromium Issue Tracker Entry.
Attack Vector
Exploitation requires a remote attacker to host a crafted HTML page and persuade a user to visit it. Once the user performs the required UI gestures, the page can display spoofed interface elements. Attackers typically pair this class of flaw with phishing pages that impersonate login prompts, address bar content, or security indicators. See the Google Chrome Stable Update advisory for the vendor's release notes.
No public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2024-11116
Indicators of Compromise
- Browser telemetry showing Chrome versions below 131.0.6778.69 visiting untrusted external domains
- User reports of unexpected browser UI behavior, misleading address bar content, or overlapping dialogs
- Web proxy logs referencing suspicious HTML pages that trigger multiple pointer or keyboard interactions in rapid succession
Detection Strategies
- Inventory endpoints for Chrome build versions and flag installations older than 131.0.6778.69
- Correlate phishing report data with URL access logs to identify pages leveraging UI spoofing techniques
- Monitor DNS and HTTP telemetry for newly registered domains hosting credential harvesting content
Monitoring Recommendations
- Enable browser version reporting through enterprise management tools and forward results to a central log repository
- Track user-submitted phishing incidents involving Chrome and match them against the vulnerable version range
- Review web gateway alerts for pages that request unusual interaction patterns before displaying login forms
How to Mitigate CVE-2024-11116
Immediate Actions Required
- Update Google Chrome to version 131.0.6778.69 or later on all managed endpoints
- Force a browser relaunch after deployment to ensure the patched Blink build is loaded
- Audit Chromium-based browsers in the environment and apply corresponding vendor updates
Patch Information
Google released the fix in the Chrome Stable channel update dated November 12, 2024. Administrators should refer to the Google Chrome Stable Update release notes for full version details and deployment guidance. Enterprise environments using Chrome Browser Cloud Management or group policy can accelerate rollout by enforcing minimum version requirements.
Workarounds
- Restrict browsing to trusted domains through web filtering policies until patches are applied
- Train users to verify address bar contents and to avoid interacting with pages that request unusual gesture sequences
- Disable or restrict access to unnecessary interactive web features via enterprise browser policies where feasible
