Known Exploited and Publicly Disclosed Vulnerability
§ CVE-2023-24880 Windows SmartScreen Security Feature Bypass
Vulnerability
§ CVSS 3.1 Scores: 5.4 / 5.0
§ Severity: Moderate
§ Windows 10, Windows 11, and Server 2016, Server 2019, Server 2022
§ Per Microsoft - “An attacker can craft a malicious file that would evade Mark of the Web
(MOTW) defenses, resulting in a limited loss of integrity and availability of security features
such as Protected View in Microsoft Office, which rely on MOTW tagging.”

Known Exploited Vulnerability
§ CVE-2023-23397 Windows Outlook Elevation of Privilege Vulnerability
§ CVSS 3.1 Scores: 9.8 / 9.1
§ Severity: Critical
§ Outlook 2013 & 2016, Office 2016, 2019 & LTSC 2022, Office 365 Apps
§ Per Microsoft - “An attacker who successfully exploited this vulnerability could access a
user's Net-NTLMv2 hash which could be used as a basis of an NTLM Relay attack against
another service to authenticate as the user.”

Known Publicly Disclosed Vulnerability
§ CVE-2022-43552 Open-Source Curl Remote Code Execution Vulnerability
§ CVSS 3.1 Scores: 5.9 / 5.9
§ Severity: Important
§ Windows 10, Windows 11, and Server 2016, Server 2019, Server 2022
§ Per NIST - “A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel*
virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do)
deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or
TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer
shutdown code path.”

Reissued Microsoft Exchange Update
§ Description of the security update for Microsoft Exchange Server 2019, 2016,
and 2013: March 14, 2023 (KB 5024296)
§ CVE-2023-21707 Microsoft Exchange Server Remote Code Execution Vulnerability
§ Per Microsoft - “We are re-releasing this CVE to inform customers that there are new
updates to install for this vulnerability. A small subset of customers were experiencing
problems with Exchange Web Services due to the updates that were released in February.
The new updates address these problems. Customers who are experiencing issues with the
February updates are encouraged to install the March Exchange Server updates listed in the
Security Updates table.”
