Vulnerability Details

Scripting Engine Remote Code Execution Vulnerability

CVE-2019-1429 According to the report of the Google Threat Analysis Team, there is a vulnerability in the way the IE scripting engine handles objects in memory. An attacker can implement remote code execution if the affected browser accesses a malicious web page or opens a specially crafted Office document. At the same time, the report indicates that this patch is required even if you are not using IE. Microsoft did not provide a determination as to the nature of the vulnerability, which could be limited by other security measures.

Exchange Server Remote Code Execution Vulnerability

CVE-2019-1373 This vulnerability is an issue with Exchange Server when using PowerShell to deserialize metadata. To exploit this vulnerability, an attacker would need to convince a user to run a cmdlet through PowerShell. This situation is demanding, but if the user does this easily, the server’s full control can be handed over to the attacker.

UAC privilege elevation vulnerability

A vulnerability in the CVE-2019-1388UAC prompt. The vulnerability reported by ZDI requires complex pre-steps in actual use. Allows attacker permissions to be promoted to NT AuthoritySYSTEM if the attack is successful.
