Microsoft addresses 87 CVEs and one advisory (ADV240001) in its November 2024 Patch Tuesday release, with four critical vulnerabilities and four zero-day vulnerabilities, including two that were exploited in the wild.
Microsoft patched 87 CVEs in its November 2024 Patch Tuesday release, with four rated critical, 82 rated important and one rated moderate.
This month’s update includes patches for:
Remote code execution (RCE) vulnerabilities accounted for 58.6% of the vulnerabilities patched this month, followed by elevation of privilege (EoP) vulnerabilities at 29.9%.
Important CVE-2024-43451 | NTLM Hash Disclosure Spoofing VulnerabilityCVE-2024-43451 is a NTLM hash spoofing vulnerability in Microsoft Windows. It was assigned a CVSSv3 score of 6.5 and is rated as important. An attacker could exploit this flaw by convincing a user to open a specially crafted file. Successful exploitation would lead to the unauthorized disclosure of a user’s NTLMv2 hash, which an attacker could then use to authenticate to the system as the user. According to Microsoft, CVE-2024-43451 was exploited in the wild as a zero-day. No further details about this vulnerability were available at the time this blog post was published.
This is the second NTLM spoofing vulnerability disclosed in 2024. Microsoft patched CVE-2024-30081 in its July Patch Tuesday release.
Important CVE-2024-49039 | Windows Task Scheduler Elevation of Privilege VulnerabilityCVE-2024-49039 is an EoP vulnerability in the Microsoft Windows Task Scheduler. It was assigned a CVSSv3 score of 8.8 and is rated as important. An attacker with local access to a vulnerable system could exploit this vulnerability by running a specially crafted application. Successful exploitation would allow an attacker to access resources that would otherwise be unavailable to them as well as execute code, such as remote procedure call (RPC) functions.
According to Microsoft, CVE-2024-49039 was exploited in the wild as a zero-day. It was disclosed to Microsoft by an anonymous researcher along with Vlad Stolyarov and Bahare Sabouri of Google's Threat Analysis Group. At the time this blog post was published, no further details about in-the-wild exploitation were available.
Important CVE-2024-49019 | Active Directory Certificate Services Elevation of Privilege VulnerabilityCVE-2024-49019 is an EoP vulnerability affecting Active Directory Certificate Services. It was assigned a CVSSv3 score of 7.8 and is rated as important. It was publicly disclosed prior to a patch being made available. According to Microsoft, successful exploitation would allow an attacker to gain administrator privileges. The advisory notes that “certificates created using a version 1 certificate template with Source of subject name set to ‘Supplied in the request’” are potentially impacted if the template has not been secured according to best practices. This vulnerability is assessed as “Exploitation More Likely” according to Microsoft’s Exploitability Index. Microsoft’s advisory also includes several mitigation steps for securing certificate templates which we highly recommend reviewing.
Important CVE-2024-49040 | Microsoft Exchange Server Spoofing VulnerabilityCVE-2024-49040 is a spoofing vulnerability affecting Microsoft Exchange Server 2016 and 2019. It was assigned a CVSSv3 score of 7.5 and rated as important. According to Microsoft, this vulnerability was publicly disclosed prior to a patch being made available. After applying the update, administrators should review the support article Exchange Server non-RFC compliant P2 FROM header detection. The supplemental guide notes that as part of a “secure by default” approach, the Exchange Server update for November will flag suspicious emails which may contain “malicious patterns in the P2 FROM header.” While this feature can be disabled, Microsoft strongly recommends leaving it enabled to provide further protection from phishing attempts and malicious emails.
Critical CVE-2024-43639 | Windows Kerberos Remote Code Execution VulnerabilityCVE-2024-43639 is a critical RCE vulnerability affecting Windows Kerberos, an authentication protocol designed to verify user or host identities. It was assigned a CVSSv3 score of 9.8 and is rated as “Exploitation Less Likely.”
To exploit this vulnerability, an unauthenticated attacker needs to leverage a cryptographic protocol vulnerability in order to achieve RCE. No further details were provided by Microsoft about this vulnerability at the time this blog was published.
Important 29 CVEs | SQL Server Native Client Remote Code Execution VulnerabilityThis month's release included 29 CVEs for RCEs affecting SQL Server Native Client. All of these CVEs received CVSSv3 scores of 8.8 and were rated as “Exploitation Less Likely.” Successful exploitation of these vulnerabilities can be achieved by convincing an authenticated user into connecting to a malicious SQL server database using an affected driver. A full list of the CVEs are included in the table below.

I didn’t see much visibility on this DocuSign hack. This is a situation where the product features were not vetted to understand if they could be misused by malicious fraudsters. There is not a technical vulnerability, it comes down to a design weakness in the product.
According to the security team at Wallarm, “An attacker creates a legitimate, paid DocuSign account that allows them to change templates and use the API directly.” They then employ a special template that masquerades as a well-known brand to send the billing invoice. Because the fraudulent invoice is directly sent from the DocuSign platform, it appears legitimate and won’t be stopped by email filters.
The entire process can be automated and sent out on a massive scale, spraying large numbers of unsuspecting victims.
It is the old story of well-intentioned developers asking if they “can” develop something without questioning if they “should” develop something.
It often takes security-minded experts, savvy in the ways of how attackers think, to evaluate such situations. These are often missed by even experienced developers because there is no technical vulnerability per se. But that does not mean a creative adversary can’t use it in destructive ways. Often, additional controls, oversight, or accountability must be included to dissuade, prevent, or quickly alert of misuse.
The sustainable solution for all software and service vendors is to have cybersecurity experts, not just security-minded developers, as part of the initial feature design teams, keep them in the loop during development, and make sure they vet the final capabilities before going live.
