Attack-Flow Graph

Executive Summary

This vulnerability is a cryptographic flaw in the WebAppInstalls component of Google Chrome on Android. It allows a local attacker to potentially escape the sandbox security feature by tricking a user into visiting a specially crafted HTML page. The flaw exists in versions of Chrome prior to 151.0.7922.72.

Detection Guidance

This vulnerability is specific to Google Chrome on Android versions prior to 151.0.7922.72. Detection involves checking the installed Chrome version. On Android, go to Settings > Apps > Chrome and verify the version number. If it is below 151.0.7922.72, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker with local access to bypass Chrome's sandbox protections. This might enable them to execute malicious code outside the browser's isolated environment, potentially accessing sensitive data or performing unauthorized actions on the device.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it involves a local sandbox escape in Google Chrome on Android. Compliance impacts would depend on specific use cases and data processing activities, not the vulnerability itself.

Mitigation Strategies

Update Google Chrome on Android to version 151.0.7922.72 or later to address the cryptographic flaw and sandbox escape risk.
