Descriptions

Microsoft Edge (Chromium-based) Spoofing Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Microsoft Edge. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the way Microsoft Edge displays a warning about hazardous downloads. A crafted file name can cause the warning message to be displayed incorrectly, misleading the user into believing that the file is harmless. An attacker can leverage this vulnerability to execute code in the context of the current user.
