Description of Critical Vulnerabilities

Microsoft fixed 15 critical vulnerabilities, five of which are described in detail as follows:

  • CVE-2020-1023, CVE-2020-1024, CVE-2020-1069, and CVE-2020–1102

These are RCE vulnerabilities in the SharePoint. Attackers could exploit these vulnerabilities to execute arbitrary code on a victim machine or server. To successfully exploit the CVE-2020-1069 vulnerability, attackers need to upload a crafted package to the SharePoint server. To exploit the CVE-2020-1023, CVE-2020-1024, and CVE-2020–1102 vulnerabilities, attackers need to trick a user into opening a crafted SharePoint file.

  • CVE-2020-1062

This is a memory corruption vulnerability in the Internet Explorer web browser. This vulnerability can be triggered when a user accesses a crafted web page controlled by the attacker. An attacker could exploit this vulnerability to corrupt the memory on the target machine and then execute arbitrary code in the context of the current user via a crafted web page. The security update addresses this vulnerability by modifying how Internet Explorer handles objects in memory.
