    descriptionThe version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 83.0.478.37. It is, therefore, affected by multiple vulnerabilities: - A use after free in media 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-2020-6466) - A use after free in WebRTC in Microsoft Edge (Chromium) allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-6467) - Type confusion in V8 in Microsoft Edge (Chromium) allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-6468) In addition, Microsoft Edge (Chromium) is also affected by several additional vulnerabilities including additional use-after-free vulnerabilties, privilege escalations, and insufficient policy enforcements.

    compromised the renderer  process to potentially perform a sandbox escape via a crafted HTML page.
