June 2022 Patch Tuesday | Microsoft Releases 55 Vulnerabilities With 3 Critical; Adobe Releases 6 Advisories, 46 Vulnerabilities With 40 Critical.

Microsoft Patch Tuesday Summary

Microsoft has fixed 55 vulnerabilities (aka flaws) in the June 2022 update, including three vulnerabilities classified as critical as they allow Remote Code Execution (RCE). This month’s Patch Tuesday cumulative Windows update includes the fix for one zero-day vulnerability (CVE-2022-30190). Microsoft also released an advisory for Intel Processor MMIO Stale Data Vulnerabilitie to address four Intel vulnerabilities (Microsoft Advisory 220002, Intel-SA-00615).

Microsoft has fixed several flaws in its software, including Denial of Service (DoS), Elevation of Privilege, Information Disclosure, Remote Code Execution (RCE), Security Feature Bypass, and Spoofing vulnerabilities.

Many of the vulnerabilities patched this month relate to remote code execution, but there are no reports of active exploitation in the wild with the exception of an update to CVE-2022-30190, a Microsoft Windows Support Diagnostic Tool (MSDT) vulnerability made public in May.

The June 2022 Microsoft Vulnerabilities Are Classified As Follows:

Exploitability Assessment: Exploitation Detected.

Windows Server 2022 Azure Edition Core Hotpatch (KB5014677) OS Build 20348.770

Windows Server 2022 Azure Edition Core Hotpatch (KB5014677) addresses 22 unique vulnerabilities, ranging in severity from a CVSSv3.1 score of 5.3/10 to 8.8/10, as summarized below.

CVE-2022-30136 | Windows Network File System Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 9.8/10.

This vulnerability 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).

Exploitability Assessment: Exploitation More Likely.

CVE-2022-30157 | Microsoft SharePoint Server Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 8.8/10.

In a network-based attack, an attacker would need to have the privileges to create a page on a vulnerable SharePoint server. By creating a site using specific code, the attacker could execute code remotely on the target server.

The attacker must be authenticated and possess the permissions for page creation to be able to exploit this vulnerability.

Exploitability Assessment: Exploitation Less Likely.

CVE-2022-30158 | Microsoft SharePoint Server Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 8.8/10.

An authenticated attacker with access to a server that has Sandboxed Code Service enabled could execute code in the context of the web service account.

The attacker must be authenticated and possess the permissions for page creation to be able to exploit this vulnerability.

Exploitability Assessment: Exploitation Unlikely.

CVE-2022-30165 | Windows Kerberos Elevation of Privilege Vulnerability

This vulnerability has a CVSSv3.1 score of 8.8/10.

Systems configured to activate both of the following features in Windows Server: CredSSP (Credential Security Service Provider) and RCG (Remote Credential Guard) might be vulnerable to this exploit.

An authenticated attacker could exploit this vulnerability to elevate privileges and then spoof the Kerberos login process when a remote credential guard connection is made via CredSSP over the network.

Exploitability Assessment: Exploitation Less Likely.

CVE-2022-30163 | Windows Hyper-V Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 8.5/10.

To exploit this vulnerability, an attacker could run a specially crafted application on a Hyper-V guest that could cause the Hyper-V host operating system to execute arbitrary code.

Successful exploitation of this vulnerability requires an attacker to win a race condition.

In this case, a successful attack could be performed from a low privilege Hyper-V guest. The attacker could traverse the guest’s security boundary to execute code on the Hyper-V host execution environment.

Exploitability Assessment: Exploitation Less Likely.

CVE-2022-30164 | Windows Kerberos AppContainer Security Feature Bypass Vulnerability

This vulnerability has a CVSSv3.1 score of 8.4/10.

A low privilege attacker could execute a script within an App Container to request a service ticket and thereby gain elevation to the service privilege.

An attacker could bypass the Kerberos service ticketing feature which performs user access control checks

In this case, a successful attack could be performed from a low privilege AppContainer. The attacker could elevate their privileges and execute code or access resources at a higher integrity level than that of the AppContainer execution environment.

Exploitability Assessment: Exploitation Less Likely.

CVE-2022-30139 | Windows Lightweight Directory Access Protocol (LDAP) Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 7.5/10.

This vulnerability is only exploitable if the MaxReceiveBuffer LDAP policy is set to a value higher than the default value. Systems with the default value of this policy would not be vulnerable.

For more information, please see LDAP policies.

Successful exploitation of this vulnerability requires an attacker to prepare the target environment to improve exploit reliability.

Exploitability Assessment: Exploitation Less Likely.

CVE-2022-30145 | Windows Encrypting File System (EFS) Remote Code Execution (RCE) Vulnerability

This vulnerability has a CVSSv3.1 score of 7.5/10.

Successful exploitation of this vulnerability requires an attacker to prepare the target environment to improve exploit reliability.

Exploitability Assessment: Exploitation Less Likely.
