0 A critical remote code execution vulnerability (CVE-2025-59287) exists in Microsoft Windows Server Update Services (WSUS) affecting versions from Windows Server 2012 through 2025 with the WSUS role enabled. This flaw allows unauthenticated attackers to execute code with system privileges by targeting exposed WSUS instances on ports 8530 and 8531. Initial patching on October 14, 2025, was incomplete, necessitating an emergency update on October 23. Exploitation has been observed within hours of patch release, with attackers leveraging malicious PowerShell commands for reconnaissance and data exfiltration. Approximately 5,500 WSUS instances are exposed globally, representing a significant attack surface. The vulnerability facilitates initial access and lateral movement within networks. European organizations using WSUS for patch management are at risk of compromise, data theft, and broader network infiltration. Immediate patching and network exposure reduction are critical to mitigate this threat. Join the discussion | AlienVault OTX General | 12/07/2025, 08:53:15 UTC Added: 12/08/2025, 18:23:52 UTC |
