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.

Executive Summary

This vulnerability is a confused deputy issue in Google Chrome's DataTransfer component. It allows an attacker who has already compromised the renderer process to potentially execute arbitrary code outside the sandbox by tricking the browser into processing a specially crafted HTML page. The attack requires user interaction and has a medium severity rating from Chromium.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 153.0.8010.36. To detect it, check your Chrome version by running chrome://version/ in the browser address bar. If your version is below 153.0.8010.36, the system is vulnerable.

This could lead to data theft, installation of malware, or further compromise of your device. The attack requires a user to visit a malicious webpage.

Compliance Impact

This vulnerability allows a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page, 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.

Mitigation Strategies
