A critical vulnerability in Windows Server Update Services (WSUS) is now actively exploited by hackers, posing significant risks to enterprise environments. This flaw allows attackers to execute remote code on affected systems, potentially leading to full system compromise. The vulnerability, tracked as CVE-2024-27512, affects multiple versions of Windows Server and has been confirmed to be exploited in the wild. Microsoft has issued security updates to address this issue, but many organizations remain vulnerable due to delayed patching. Cybercriminals are leveraging this flaw to deploy malware and gain persistent access to networks, emphasizing the urgent need for timely updates and robust security measures.
The exploitation of the WSUS flaw highlights the increasing trend of attackers targeting supply chain and update infrastructure components.
