path \\<listener>\share↗

• → Monitor for POST requests to the endpoint `ServletAPI/Reports/saveReportScheduler` containing a UNC path (e.g., `\\<attacker-IP>\share`) in the `STORAGE_PATH` parameter — this is the core exploitation step that triggers outbound NTLM authentication to an attacker-controlled SMB server. ↗
• → Alert on outbound SMB (TCP 445) connections originating from ManageEngine ADSelfService Plus / ADAuditPlus / Exchange Reporter Plus / ADManagerPlus service accounts to external or unexpected hosts, as the exploit forces the server to authenticate to an attacker SMB listener, leaking NTLMv2 hashes. ↗
• → Detect the patched-state indicator: a patched target returns the string `adssp.reports.schedule_reports.storage_path.unc_storage_path` in the response body when a UNC STORAGE_PATH is submitted. Absence of this string on vulnerable builds means the UNC path was accepted. ↗
• → Flag NTLM relay attempts: the exploit explicitly supports relaying captured hashes to SMB (`-t smb://TARGET`) or LDAP/LDAPS (`-t ldaps://TARGET`) via ntlmrelayx, so monitor for unexpected NTLM authentications on internal SMB/LDAP services. ↗

• · The vulnerability affects multiple ManageEngine products across different version thresholds; ensure patching covers all affected products (ADSelfService Plus < 6121, ADAuditPlus < 7060, Exchange Reporter Plus < 5701, ADManagerPlus < 7131). ↗
• · The exploit requires valid application credentials (either an ADSelfService Plus local account or a domain user account) to authenticate before triggering the NTLM leak — the vulnerability is exploitable by authenticated low-privileged users, not just admins. ↗
• · The NTLMv2 hash capture is not immediate; the scheduled report fires approximately every 5 minutes, meaning defenders have a short window to detect the malicious scheduler entry before hash exfiltration occurs. ↗
