Microsoft addressed a total of 130 vulnerabilities in its latest Patch Tuesday initiative. A significant vulnerability in SQL Server, identified as CVE-2025-49719, has a CVSS score of 7.5 and is due to improper input validation, potentially allowing unauthorized access to sensitive data. It affects SQL Server versions from 2016 to 2022. Another critical vulnerability, CVE-2025-47981, has a CVSS score of 9.8 and allows unauthenticated remote code execution without user interaction. This vulnerability poses a high risk due to its low attack complexity and potential for lateral movement within networks. Additionally, the update includes 16 vulnerabilities affecting Microsoft Office, with four categorized as more likely to be exploited.

Manufacturers are increasingly integrating IT systems with operational technology (OT), leading to heightened cyber threats such as ransomware, supply chain breaches, and attacks from nation-state actors. To enhance cyber resilience, it is crucial to segment IT and OT networks to prevent breaches on the IT side from affecting critical OT systems. Effective segmentation involves placing OT systems behind firewalls, restricting protocols, and using unidirectional gateways. Many manufacturing plants struggle with aging and undocumented devices, making security and monitoring challenging. Asset visibility tools can help map connected devices, enabling better inventory management and risk assessment. Attackers often use "living-off-the-land" techniques to navigate networks undetected, necessitating defenses that include behavioral analytics and application whitelisting. Incident response plans tailored for OT environments are essential, as production interruptions can have severe consequences. These plans should include scenarios like ransomware attacks and require regular testing and backups. For legacy systems that cannot be patched, isolation and monitoring are critical, along with virtual patching to block known exploits. Weak credentials pose a significant risk, so implementing role-based access control and multi-factor authentication is necessary. Security monitoring tools like SIEM and XDR should be used to consolidate data from IT and OT environments, providing alerts for potential attacks. Overall, cyber resilience in manufacturing focuses on minimizing risks and ensuring recovery without disrupting operations.

Microsoft has resolved an issue that affected the delivery of Windows 11 24H2 feature updates via Windows Server Update Services (WSUS) after the installation of the April 2025 security updates. Users reported upgrade problems, specifically encountering error code 0x80240069 during attempts to update from Windows 11 23H2 or 22H2. The update complications primarily impact enterprise environments using WSUS, while home users are less likely to experience these issues. Microsoft is rolling out a fix through Known Issue Rollback (KIR) for enterprise-managed devices, requiring IT administrators to implement the KIR Group Policy on affected endpoints. Additionally, Microsoft is addressing a separate issue where some PCs were upgraded to Windows 11 despite Intune policies preventing such upgrades.

Microsoft has acknowledged a significant issue affecting enterprise users trying to upgrade to Windows 11 24H2 via Windows Server Update Services (WSUS) after installing the April 2025 security updates, specifically the monthly security update KB5055528. Users with Windows 11 23H2 or 22H2 are encountering Windows Update Service errors with the code 0x80240069, preventing the download process for Windows 11 24H2 from initiating or completing. Microsoft confirmed that devices with the April security update might be unable to update via WSUS. WSUS, primarily used in enterprise settings, has been deprecated as of September 2024, but Microsoft will continue to support existing functionalities. Additionally, Microsoft is addressing a "latent code issue" that has caused some devices to upgrade to Windows 11 despite Intune policies against such upgrades.

Microsoft has indefinitely postponed the removal of driver synchronization within Windows Server Update Services (WSUS) in response to customer feedback. The planned removal, originally set for April 18, 2025, has been put on hold as the company works on a revised timeline. This decision marks a shift from previous communications that indicated the deprecation of WSUS driver synchronization. Microsoft had initially announced the intention to phase out this feature in June 2024 and had encouraged IT administrators to adopt cloud-based solutions. Despite the earlier deprecation announcement, Microsoft will continue to support existing WSUS capabilities and publish updates.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical alert about a command injection vulnerability (CVE-2023-20118) affecting Cisco Small Business RV Series Routers, which are end-of-life. This vulnerability, rated 6.5 on the CVSSv3.1 scale, allows authenticated attackers to execute arbitrary commands with root privileges. The affected models include RV016, RV042, RV042G, RV082, RV320, and RV325, running firmware versions released before April 2023. Cisco will not provide patches for these devices. CISA mandates that federal agencies either implement mitigations or stop using the routers by March 24, 2025. Private organizations are also encouraged to address the issue, especially due to exploitation attempts linked to the PolarEdge botnet campaign. Administrators are advised to restrict administrative access, monitor logs for unusual activity, and consider decommissioning affected devices. The continued use of unpatched routers poses significant risks to critical infrastructure, particularly in small business and remote work environments.

A report from Microsoft reveals that the Russian state-sponsored threat group known as Seashell Blizzard has shifted its operational focus to exploiting public vulnerabilities in internet-facing systems. This subgroup, associated with the Russian Military Intelligence Unit 74455 (GRU), has been conducting operations under the "BadPilot campaign," allowing them to maintain long-term access to compromised systems since at least 2021. They have been responsible for at least three destructive cyberattacks in Ukraine since 2023 and are now targeting a broader range of industries globally, including energy, telecommunications, and government sectors. Since early 2024, they have exploited vulnerabilities in software such as ConnectWise ScreenConnect and Fortinet FortiClientEMS, indicating a "spray and pray" approach to achieve compromises at scale. The group has adapted to exploit various public vulnerabilities, including critical issues in applications like Microsoft Exchange and Zimbra Collaboration, demonstrating their capability to leverage weaknesses in essential systems. Microsoft describes Seashell Blizzard as a key component of Russia's cyber strategy, particularly in efforts to destabilize Western institutions.
