Microsoft Patch Tuesday security updates for March 2024 addressed 59 security vulnerabilities in its products, including RCE flaws.
Microsoft released Patch Tuesday security updates for March 2023 that address 59 security vulnerabilities in its products.
The IT giant addressed vulnerabilities in Microsoft Windows and Windows Components; Office and Office Components; Azure; .NET Framework and Visual Studio; SQL Server; Windows Hyper-V; Skype; Microsoft Components for Android; and Microsoft Dynamics. The company also fixed five additional Chromium flaws.
Two of the vulnerabilities, tracked as CVE-2024-21407 and CVE-2024-21408, addressed by Microsoft are rated Critical, while the remaining 57 issues are rated Important in severity.
The vulnerability CVE-2024-21407 is a Remote Code Execution issue in the Windows Hyper-V.
“This vulnerability would require an authenticated attacker on a guest VM to send specially crafted file operation requests on the VM to hardware resources on the VM which could result in remote code execution on the host server.” reads the advisory. “Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment and take additional actions prior to exploitation to prepare the target environment.”
The vulnerability CVE-2024-21408 is a Denial of Service issue in the Windows Hyper-V.
The most severe vulnerability addressed by Microsoft is an Open Management Infrastructure (OMI) Remote Code Execution Vulnerability tracked as CVE-2024-21334 (CVSS score 9.8).
A remote, unauthenticated attacker can trigger this vulnerability to execute code on OMI instances accessible via the Internet.
“It’s not clear how many of these systems are reachable through the Internet, but it’s likely a significant number. Microsoft gives this an “Exploitation less likely” rating, but considering this is a simple Use After Free (UAF) bug on a juicy target, I would expect to see scanning for TCP port 5986 on the uptick soon.” reported ZDI.
The good news is that none of the vulnerabilities fixed by Microsoft Patch Tuesday security updates for March 2023 are listed as publicly known or under active attack.
Microsoft also addressed a Microsoft Azure Kubernetes Service Confidential Container Elevation of Privilege Vulnerability tracked as CVE-2024-21400.
