Zero-day Vulnerabilities Patched in June Patch Tuesday Edition
CVE-2023-50868: MITRE: CVE-2023-50868 NSEC3 closest encloser proof can exhaust CPU
The vulnerability exists in DNSSEC validation that may allow an attacker to exploit standard DNSSEC protocols intended for DNS integrity by using excessive resources on a resolver, causing a denial of service for legitimate users. This vulnerability was disclosed in February and patched in numerous DNS implementations.
Critical Severity Vulnerability Patched in June Patch Tuesday Edition
CVE-2024-30080: Microsoft Message Queuing (MSMQ) Remote Code Execution Vulnerability
Message Queuing (MSMQ) is a protocol developed by Microsoft to ensure reliable communication between Windows computers across different networks, even when a host is temporarily not connected (by maintaining a message queue of undelivered messages). To exploit this vulnerability, an attacker must send a malicious MSMQ packet to an MSMQ server. On successful exploitation, an attacker may perform remote code execution on the server side.
Other Microsoft Vulnerability Highlights
- CVE-2024-30082 is an elevation of privilege vulnerability in Win32k. An attacker who successfully exploits the vulnerability may gain SYSTEM privileges.
- CVE-2024-35250 is an elevation of privilege vulnerability in the Windows Kernel-Mode Driver. On successful exploitation, an attacker may gain SYSTEM privileges.
- CVE-2024-30084 is an elevation of privilege vulnerability in the Windows Kernel-Mode Driver. To exploit the vulnerability, an attacker must win a race condition. On successful exploitation, an attacker may gain SYSTEM privileges.
- CVE-2024-30085 is an elevation of privilege vulnerability in the Windows Cloud Files Mini Filter Driver. An attacker who successfully exploits the vulnerability may gain SYSTEM privileges.
- CVE-2024-30086 is an elevation of privilege vulnerability in the Windows Win32 Kernel Subsystem. On successful exploitation, an attacker may gain SYSTEM privileges.
- CVE-2024-30087 is an elevation of privilege vulnerability in the Win32k. The attacker would gain the rights of the user running the affected application.
- CVE-2024-30089 is an elevation of privilege vulnerability in the Microsoft Streaming Service. On successful exploitation, an attacker may gain SYSTEM privileges.
- CVE-2024-30091 is an elevation of privilege vulnerability in Win32k. The attacker would gain the rights of the user running the affected application.
- CVE-2024-30088 and CVE-2024-30099 are elevation of privilege vulnerabilities in the Windows Kernel. To exploit them, an attacker must win a race condition. On successful exploitation, an attacker may gain SYSTEM privileges.

Discover and Prioritize Vulnerabilities in Vulnerability Management, Detection & Response (VMDR)
Qualys VMDR automatically detects new Patch Tuesday vulnerabilities using continuous updates to its Knowledgebase (KB).
You can see all your impacted hosts by these vulnerabilities using the following QQL query:
vulnerabilities.vulnerability: ( qid:`110467` OR qid:`110468` OR qid:`110469` OR qid:`379940` OR qid:`92142` OR qid:`92143` OR qid:`92144` OR qid:`92145` )
Rapid Response with Patch Management (PM)
VMDR rapidly remediates Windows hosts by deploying the most relevant and applicable per-technology version patches. You can simply select respective QIDs in the Patch Catalog and filter on the “Missing” patches to identify and deploy the applicable, available patches with one click.
The following QQL will return the missing patches for this Patch Tuesday:
( qid:`110467` OR qid:`110468` OR qid:`110469` OR qid:`379940` OR qid:`92142` OR qid:`92143` OR qid:`92144` OR qid:`92145`)
EVALUATE Vendor-Suggested Mitigation with Policy Compliance (PC)
With Qualys Policy Compliance’s Out-of-the-Box Mitigation or Compensatory Controls, the risk of a vulnerability being exploited is reduced when the remediation (fix/patch) cannot be implemented immediately.
Qualys Policy Compliance team releases these exclusive controls based on vendor-suggested Mitigation/Workaround.
Mitigation refers to a setting, standard configuration, or general best-practice existing in a default state that could reduce the severity of the exploitation of a vulnerability.
A workaround is sometimes used temporarily to achieve a task or goal when the usual or planned method isn’t working. Information technology often uses a workaround to overcome hardware, programming, or communication problems. Once a problem is fixed, a workaround is usually abandoned.
The following Qualys Policy Compliance Control IDs (CIDs), and System Defined Controls (SDC) have been updated to support Microsoft recommended mitigation(s) for this Patch Tuesday:
CVE-2024-30080: Microsoft Message Queuing (MSMQ) Remote Code Execution Vulnerability
CVSS:3.1 9.8 / 8.5 Policy Compliance Control IDs (CIDs):
- 14297 Status of the open network connections and listening ports (Qualys Agent only)
- 14916 Status of Windows Services
- 4030 Status of the Windows Message Queuing Service
The following QQL will return a posture assessment for the CIDs for this Patch Tuesday: control.id: [14297, 14916, 4030] 
CVE-2024-30070: DHCP Server Service Denial of Service Vulnerability
CVSS:3.1 7.5 / 6.7 Policy Compliance Control IDs (CIDs):
