Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only. What cve.now has for CVE-2026-75869 (entry last updated 2026-11-12): Affected: - Zohocorp DDI Central: fixed in 6301 Fixed versions: 6301. Conditions (all must be true for the bug to be hit): - ManageEngine DDI Central 6.3.0 build 6300 and below (source: https://www.manageengine.com/dns-dhcp-ipam/security-updates/cve-2026-75869.html) - Windows DHCP DNS settings configuration workflow with managed Windows DHCP servers (source: https://www.manageengine.com/dns-dhcp-ipam/security-updates/cve-2026-75869.html) Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. Attacker needs: network access, low-privilege login, no user action. CISA KEV: CVE-2026-75869 is not listed as of cve.now's last read. This KEV status is for CVE-2026-75869 only. If you also check another CVE, look up its own KEV status; never assume it from this one. How to check: - Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory. Verify against the linked advisories before concluding, and cite the date you read each one: - https://www.manageengine.com/dns-dhcp-ipam/security-updates/cve-2026-75869.html Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing. Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked. Source: https://cve.now/CVE-2026-75869 ### What does this mean? An authenticated user of DDI Central can send attacker-controlled PowerShell commands to a Windows DHCP server outside the operator's authorized cluster. The commands run in the context of the DDI Central Windows management service account.
