Patch Tuesday, May 2025 – Krebs

Microsoft Software update released Tuesday to resolve at least 70 vulnerabilities Windows and related products, including Five zero-day defects have seen active exploitation. In addition to the urgency of Redmond’s patch batch this month, two other weaknesses are addressed that now have public proof of concept exploitation.
Microsoft and several security companies reveal that attackers are exploiting a pair of bugs Windows Universal Log File System (CLFS) drivers that allow attackers to enhance their privileges on vulnerable devices. Windows CLFS is a key Windows component responsible for logging services and is widely used by Windows System Services and third-party applications. Tracked as CVE-2025-32701 and CVE-2025-32706, these defects are present in all supported versions of Windows 10 and 11, as well as their server versions.
Kev BreenSenior Director of Threat Research Immersive lab,The privilege escalation error assumes that an attacker can typically access the compromised host through phishing attacks or using stolen credentials. However, if that access is already present, an attacker can use the credential harvesting tool to access a more powerful Windows system account, which can disable security tools or even gain domain management level permissions.
“The patch notes don’t provide technical details on how to exploit this, nor do they share metrics of compromise (IOC), which means the only mitigation team is to apply these patches immediately,” he said. “The average time from public disclosure to mass exploitation is less than five days, threatening players, ransomware groups and members quickly exploit these vulnerabilities.”
The other two zero days patched by Microsoft today also include the privilege level: CVE-2025-32709, involving Afd.Sys, The Windows Accessibility Driver This enables Windows applications to connect to the Internet; and CVE-2025-30400, Weakness Desktop Window Manager (DWM) Windows library.

After negative feedback from security experts, Microsoft returned to the recall board, which warned that it would bring an attractive target and provide potential gold mines for attackers. Microsoft seems to have worked hard to stop the recall of sensitive financial information, but privacy and security issues continue. Former Microsoftie Kevin Beaumont Microsoft’s update needs memories.
