Moderate CVSS 2.4 📢 Publicly disclosed 2018-02 archive

Executive Summary

A security feature bypass vulnerability exists when Microsoft Edge improperly handles requests of different origins. The vulnerability allows Microsoft Edge to bypass Same-Origin Policy (SOP) restrictions, and to allow requests that should otherwise be ignored. An attacker who successfully exploited the vulnerability could force the browser to send data that would otherwise be restricted. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. The attacker could also take advantage of compromised websites, and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability. The security update addresses the vulnerability by modifying how affected Microsoft Edge handles different-origin requests.
