Exploitability

CWE

KEV

CWE ID	Description
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CWE-20	The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

Attack-Flow Graph

Executive Summary

This vulnerability involves improper input validation in the Date handling feature of Google Chrome versions before 156.0.8078.47. A remote attacker could exploit this by crafting a malicious HTML page to potentially execute arbitrary code outside the browser's sandbox, leading to significant security risks.

Detection Guidance

I don't know

Detection requires checking the installed version of Google Chrome. Compare the version against 156.0.8078.47 or later. Use commands like 'google-chrome --version' or check via package manager (e.g., 'apt list --installed | grep chrome' on Debian/Ubuntu).

If the version is below 156.0.8078.47, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device, bypassing security restrictions. This might lead to unauthorized access to sensitive data, installation of malware, or complete system compromise. Users should update Chrome immediately to mitigate the risk.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code outside the sandbox via crafted HTML pages, which could lead to unauthorized data access or manipulation. Such risks may impact compliance with GDPR (data protection) and HIPAA (health data security) by potentially exposing sensitive information or violating integrity requirements.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later immediately. Disable automatic updates temporarily if needed to verify the update before enabling them again.

Avoid visiting untrusted websites or opening suspicious HTML files until the update is applied.
