In-The-Wild & Disclosed CVEs

CVE-2018-8278

Microsoft Edge is vulnerable to a spoofing vulnerability that could allow an attacker to design a malicious fake website that appears to be legitimate. This is due to how Microsoft Edge handles HTML content.

Microsoft has rated this as a 1 on the Exploitability Index (Exploitation More Likely).

CVE-2018-8313

A privilege escalation within the Windows Kernel API could allow attackers to impersonate processes, interject cross-process communication, or interrupt system functionality. This attack requires that an authenticated, local user run a purpose-built application. Changes were made to how the Windows Kernel API enforces permissions to resolve this vulnerability.

Microsoft has rated this as a 1 on the Exploitability Index (Exploitation More Likely).

CVE-2018-8314

Attackers can escalate privileges and escape a sandbox due to failure in how Windows file picker handles paths. This could allow an attacker to gain higher levels of access but does not specifically allow code execution, attackers would need to pair this attack with another vulnerability if code execution is the desired goal.

Microsoft has rated this as a 1 on the Exploitability Index (Exploitation More Likely) for older software releases (the latest software release is not affected).
