Microsoft addressed three Critical remote code execution (RCE) vulnerabilities:
- CVE-2022-30136: Windows Network File System Remote Code Execution Vulnerability (CVSS 9.8)
- CVE-2022-30139: Windows Lightweight Directory Access Protocol (LDAP) Remote Code Execution Vulnerability (CVSS 7.5)
- CVE-2022-30163: Windows Hyper-V Remote Code Execution Vulnerability (CVSS 8.5).
Microsoft warned CVE-2022-30136 “could be exploited over the network by making an unauthenticated, specially crafted call to a Network File System (NFS) service to trigger a Remote Code Execution (RCE).”
Moreover, Microsoft confirmed the vulnerability is “more likely” of being exploited.
CVE-2022-30139 is only exploitable if the MaxReceiveBuffer LDAP policy is set to a value higher than the default value. However, systems with the policy set to the default value would not be vulnerable.
In addition, Microsoft patched 52 other vulnerabilities rated Important in multiple products. Those issues include Denial of Service, Elevation of Privilege, Information Disclosure, RCE, and Security Feature Bypass Spoofing vulnerabilities.
Just last month, Microsoft also issued a workaround for a vulnerability in its Microsoft Support Diagnostic Tool (MSDT) dubbed “Follina” in Windows.
On May 30, 2022, Microsoft released the guidance for the MSDT remote code execution vulnerability CVE-2022-30190 (CVSS 7.8). A remote, unauthenticated attacker could exploit this vulnerability to take control of an impacted system.
Last week, the software giant also exposed and disabled a Lebanon-based Polonium cyber activity targeting Israeli organizations.
According to Microsoft Threat Intelligence Center (MSTIC), the bad actors created 20 malicious OneDrive applications used to target organizations in Israel with a focus on critical manufacturing, IT, and Israel’s defense industry.
