CVE-2025-29810: 
vulnerability analysis and mitigation

Microsoft disclosed a high-risk security vulnerability (CVE-2025-29810) in Windows Active Directory Domain Services (AD DS) on April 8, 2025. The vulnerability affects Windows Server editions from 2016 through 2025 and is rated as Important with a CVSS v3.1 score of 7.5. This flaw is classified under CWE-284 (Improper Access Control) and allows an authorized attacker with low-privilege access to elevate privileges over a network (GBHackers, NVD).

The vulnerability stems from improper access control in Active Directory's authentication protocols. The flaw specifically involves misconfigured security descriptors that can be exploited by attackers with standard user accounts. The attack vector operates over network-accessible pathways and requires no user interaction, making it particularly concerning for enterprise environments (GBHackers).

If successfully exploited, the vulnerability could lead to full domain compromise. Attackers could perform credential harvesting, establish persistent backdoors, and cause operational disruption. The elevated privileges gained through exploitation could enable lateral movement throughout the network, data theft, or potential ransomware deployment (GBHackers).

Microsoft has released a patch as part of the April 2025 security updates (KB5036789). Organizations are advised to implement immediate patching, conduct AD permissions audits using tools like ACL Scanner, enforce Zero Trust principles through network segmentation and multi-factor authentication, and monitor authentication logs for unusual account modifications or privilege changes (GBHackers).

Cybersecurity expert Priya Sharma of CERT-In emphasized the severity of the vulnerability, stating 'This vulnerability undermines the trust model of Active Directory.' The disclosure comes amid a reported 30% year-over-year increase in AD-targeted attacks since 2023, according to Microsoft's Digital Defense Report (GBHackers).
