CVE-2025-62215, 60274, 62199 - Microsoft Patch Tuesday Trio

CVE-2025-62215, CVE-2025-60274, and CVE-2025-62199 headline Microsoft’s November 2025 Patch Tuesday, addressing more than 60 vulnerabilities across all supported Windows versions and key enterprise products. CVE-2025-62215 is a Windows memory corruption zero-day already under active exploitation, while CVE-2025-60274 impacts the ubiquitous GDI+ graphics library and CVE-2025-62199 affects Microsoft Office with a remote code execution path triggered by previewing malicious content. These vulnerabilities span Windows OS, Office, SQL Server, SharePoint, Visual Studio, GitHub Copilot, and Azure Monitor Agent, mapping primarily to T1203 (Exploitation for Client Execution) and T1190 (Exploit Public-Facing Application). Together, this Patch Tuesday release forms a critical update bundle for any organization running Windows 10 or newer, as well as mixed on-prem and cloud workloads. The zero-day CVE-2025-62215 requires an attacker to already have local access, but it can be chained with initial access techniques to escalate privileges or gain deeper control over a compromised Windows host. By contrast, CVE-2025-60274 in GDI+ offers a 9.8-rated critical remote code execution scenario for any application that processes crafted image content, including Office, web applications, and third-party software that relies on the graphics stack. CVE-2025-62199 in Office can be exploited with low complexity, no privileges, and even via the Preview Pane, making it ideal for spear-phishing campaigns that deliver booby-trapped documents. These three Microsoft vulnerabilities represent classic Patch Tuesday risk: broad attack surface, widely deployed components, and high-value endpoints. From a business impact perspective, failure to deploy these Microsoft Patch Tuesday updates exposes organizations to ransomware, data breaches, and business email compromise, as attackers routinely reverse-engineer patches and weaponize exploit code. Environments still relying on Windows 10 are particularly at risk, because enterprises often delay upgrades and may misunderstand extended update eligibility, leaving large populations of endpoints partially patched or unpatched. Regulatory obligations under GDPR, PCI-DSS, and sectoral rules can come into play if exploitation of Office or Windows vulnerabilities leads to compromise of customer data or payment card information. Microsoft has released security updates for all affected platforms, including a fix for enrollment issues in the Windows 10 Consumer Extended Security Update program that previously blocked some users from receiving patches. Security teams should prioritize patching for CVE-2025-60274 and CVE-2025-62199 on systems processing untrusted documents or images, while also closing the zero-day escalation path in CVE-2025-62215. Enterprises should verify that Windows 10 devices are properly enrolled to receive the extra year of updates, coordinate with change management to deploy patches across servers and endpoints, and monitor for exploit attempts targeting GDI+ and Office components in email and web traffic.
