Official Module Sample
CVE-2026-41089 - Netlogon Stack Buffer Overflow
This is a production-style module page template for third-party developers in the AI Security Tool ecosystem. It combines technical clarity, user guidance, and required cross-linking in a single consistent layout.
Severity Overview
Vulnerability profile
Business impact
Successful exploitation may allow full domain controller compromise, lateral movement, and direct access to identity infrastructure.
Operational relevance
Netlogon exposure is high-priority for SOC and IR teams because attack traffic can blend with domain communication patterns.
Threat Model
Attack scenario
- 1. Discovery: attacker locates a reachable domain controller endpoint.
- 2. Trigger: crafted Netlogon request causes stack corruption in vulnerable processing path.
- 3. Execution: memory corruption enables arbitrary code execution context.
- 4. Expansion: attacker pivots to full Active Directory takeover and persistence.
Detection
Indicators of compromise and hunting guidance
Primary signals
- Unexpected Netlogon instability or restart behavior.
- Suspicious child process behavior linked to lsass.exe.
- Anomalous burst of RPC requests against domain controllers.
Telemetry priorities
- Windows Security Events and service-failure logs.
- Sysmon process and network event correlation.
- Identity threat telemetry from directory-aware sensors.
Hardening
Mitigation checklist
- 1. Apply latest Microsoft security updates on all domain controllers.
- 2. Restrict Netlogon and related RPC exposure to trusted network segments.
- 3. Enable high-sensitivity behavior monitoring around identity-critical processes.
- 4. Add update subscriptions via the central updates center.

Ecosystem Standard
Required cross-linking for third-party module pages
Every module page must include these links for ecosystem consistency and centralized support routing:
- 1. Developer module repository: canonical implementation source.
- 2. Main platform repository: ZeroDayEvil/ai-security-tool.
- 3. Main website: zerodayevil.github.io/ai-security-tool.
- 4. Central updates center: updates page.
