⚡ TL;DR | Go Straight to the April 2024 Patch Tuesday Audit Report
Patch Tuesday is once again upon us. As always, our team has put together the monthly Patch Tuesday Report to help you manage your update progress. The audit report gives you a quick and clear overview of your Windows machines and their patching status. The April 2024 edition of Patch Tuesday brings us 151 new fixes, with 3 rated as critical. We’ve listed the most important changes below.
Microsoft Defender for IoT Vulnerabilities
All critical vulnerabilities this month are part of Microsoft Defender for IoT. CVE-2024-21322, CVE-2024-21323 and CVE-2024-29053 while three additional less critical vulnerabilities were also fixed (CVE-2024-21324, CVE-2024-29055, CVE-2024-29054).
Obviously you have to be using this product in order to be affected. More specifically, you’ll need to be using the legacy on-premises management console.
All three critical vulnerabilites have slighly different requirements ranging from requiring the attacker to be an administrator to any authenticated attacker could trigger the vulnerability.
SmartScreen Prompt Security Feature Bypass Vulnerability
The second high profile fix is a security bypass vulnerability for SmartScreen. Microsoft Defender SmartScreen helps protect you from online threats like malware and phishing by checking websites and downloaded files against a database of unsafe ones. To exploit this security feature bypass vulnerability, an attacker would need to convince a user to launch malicious files using a launcher application that requests that no UI be shown.
CVE-2024-29988 has a CVSS score of 8.8 and Microsoft lists it as one of the vulnerabilities that is more likely to be exploited.
Multiple Elevation of Privilege Vulnerabilities
The large majority of vulnerabilities marked by Microsoft as “more liekly” to be exploited this month are elevation of privilege vulnerabilities that all can lead to the attacker gaining SYSTEM privileges. Their CVSS base scores are all 7.8 and Microsoft has not provided any additional information at this time.
- CVE-2024-26158 (Microsoft Install Service Elevation of Privilege Vulnerability)
- CVE-2024-26218 (Windows Kernel Elevation of Privilege Vulnerability)
- CVE-2024-26241 (Win32k Elevation of Privilege Vulnerability)
- CVE-2024-26211 (Windows RAC Manager Elevation of Privilege Vulnerability)
- CVE-2024-26230 (Windows Telephony Server Elevation of Privilege Vulnerability)
- CVE-2024-26239 (Windows Telephony Server Elevation of Privilege Vulnerability)
Run the Patch Tuesday April 2024 Audit
To help manage your update progress, we’ve created the Patch Tuesday Audit that checks if the assets in your network are on the latest patch updates. The report has been color-coded to see which machines are up-to-date and which ones still need to be updated. As always, system administrators are urged to update their environment as soon as possible to ensure all endpoints are secured.
The Lansweeper Patch Tuesday report is automatically added to your Lansweeper Site. Lansweeper Sites is included in all our licenses without any additional cost and allows you to federate all your installations into one single view so all you need to do is look at one report, automatically added every patch Tuesday!
