The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 81.0.416.68. It is, therefore, affected by multiple vulnerabilities:
A use after free in storage in Microsoft Edge (Chromium) allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (CVE-2020-6461)
A use after free in task scheduling in Microsoft Edge (Chromium) allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (CVE-2020-6462)
