Executive Summary

This is an authentication bypass vulnerability in Zohocorp ManageEngine DDI Central versions below 6301. It allows unauthenticated users to impersonate onboarded Windows servers via Windows DNS and DHCP agent synchronization APIs. The system fails to properly authenticate requests and relies on the server_ip value in HTTP requests to identify agents, enabling unauthorized modifications to DNS and DHCP data.

Detection Guidance

Check if your ManageEngine DDI Central version is below 6301 by reviewing the build number in the console or logs. Monitor network traffic for unauthorized synchronization requests to Windows DNS and DHCP agent APIs, particularly those lacking proper authentication headers or containing manipulated server_ip values in HTTP request bodies.

Impact Analysis

An attacker could exploit this to create, modify, or delete DHCP subnet information, DNS zones, DNS zone scopes, and DNS records. This may lead to DHCP subnet scope deletion or modification, unauthorized DNS changes, DNS traffic redirection, incorrect network configuration, or disruption of DNS and DHCP management operations.

Mitigation Strategies

Immediately update ManageEngine DDI Central to build 6301 or later to enforce authentication checks on synchronization APIs. Verify all Windows Node Agents are running the updated version. Block unauthorized API access attempts and review DNS/DHCP configurations for unauthorized changes.
