GermanyMicrosoft has warned administrators about the emergence of proof-of-concept exploit code for a critical vulnerability in its Active Directory Certificate Services (AD CS), known as 'Certighost' (CVE-2026-54121). This vulnerability allows authenticated users to manipulate machine account attributes and obtain certificates that enable authentication as a domain controller, potentially allowing attackers to perform unauthorized AD operations. The vulnerability was patched during Microsoft’s July security update, but the release of detailed exploit code increases the risk of attacks. Microsoft recommends immediate installation of the July patches, especially on servers hosting Enterprise Certification Authorities, to prevent exploitation. Additionally, administrators who cannot apply updates immediately are advised to enable audit logging to detect suspicious certificate-related activities.
