The version of Microsoft Edge (Chromium) installed on the remote Windows host is prior to 79.0.309.68. It is, therefore, affected by multiple vulnerabilities:
A spoofing vulnerability exists in the Windows CryptAPI due to how it validates Elliptic Curve Cryptography (ECC) certificates. An unauthenticated, remote attacker can exploit this, by using a spoofed code-signing certificate to sign a malicious executable, to make the executable appear like it is from a trusted, legitimate source. (CVE-2020-0601)
A use-after-free vulnerability exists in the speech component of Google Chrome. An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
(CVE-2020-6378)
A use-after-free vulnerability exists in the V8 component of Google Chrome. An unauthenticated, remote attacker can exploit this, via a crafted HTML page, to potentially exploit heap corruption.
(CVE-2020-6379)
An insufficient policy enforcement vulnerability exists in Google Chrome. An authenticated, remote attacker that has compromised the renderer process can exploit this, via a crafted Chrome Extension, to bypass site isolation. (CVE-2020-6380)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
