Exploitability

CWE

CWE ID Description
CWE-441 The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor.
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability is a use-after-free issue in WebAppInstalls in Google Chrome versions before 156.0.8078.47. A use-after-free occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution. In this case, a remote attacker could exploit this by crafting a malicious HTML page to trigger the flaw.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 156.0.8078.47. Detection involves checking the installed Chrome version. On Windows, Linux, or macOS, open Chrome and go to chrome://settings/help to see if updates are pending or installed. If the version is below 156.0.8078.47, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to execute arbitrary code on your system. This could lead to unauthorized access, data theft, or installation of malware. Since it affects Chrome, users browsing untrusted websites are at risk if their browser is outdated.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages. While not directly tied to compliance standards, such vulnerabilities could lead to unauthorized data access or processing, which may violate GDPR (data protection) or HIPAA (health data privacy) if exploited.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later to address the use after free vulnerability in WebAppInstalls.
