DDI CENTRAL LINUX NODE AGENT · CVE-2026-95651 · Vendor
FIX → build 6500 ✓ verified
Linux Node Agent builds 6301 and below accepted a GSS-TSIG keytab update without authentication. A network client that could reach the agent listener could replace the active BIND keytab and trigger a BIND reload. Zoho says arbitrary DNS updates were not demonstrated. Fixed in build 6500 (Sept 17, 2026).

Teams running ManageEngine DDI Central with the Linux Node Agent (managing BIND) on build 6301 or earlier. It matters most where GSS-TSIG secure dynamic DNS (Windows AD integration) is used and the agent listener is reachable by untrusted network clients. Windows-only agent deployments or builds 6500+ can skip it.
Not affected if build-6500-or-later, no-gss-tsig, no-linux-node-agent
