Exploitability

CWE

KEV

CWE ID	Description
CWE-862	The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in Chromecast within 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. An attacker could exploit this by tricking a user into visiting a specially crafted HTML page, which might allow code to run inside the browser's sandbox.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 156.0.8078.47. To detect it, check your Chrome version by running chrome://version/ in the browser. If your version is below 156.0.8078.47, update Chrome immediately. No direct network detection commands are provided for this issue.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to execute arbitrary code on your device through a malicious webpage. Since it affects Chromecast in Chrome, it might compromise the browser's sandbox, potentially leading to unauthorized access or control of your system. Users should update Chrome to the latest version to mitigate this risk.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages, which could lead to unauthorized data access or manipulation. This may violate GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information if exploited in systems handling such data.

Mitigation Strategies

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