|
| Exploitation Conditions | Requires a valid low-privilege authenticated account (PR:L) on ManageEngine OpManager or Firewall Analyzer at version 12.8.710 or below; the attacker must reference Change Management report-schedule configurations for firewalls outside their own assigned scope. No user interaction is needed and the vector is network-based over the product's web interface. Exploitation is limited by the need for pre-existing account access and by deployments that actually segment firewalls across scopes/tenants - a single-scope or single-admin install has little to steal cross-scope. |
| Impact | The vendor CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N = 7.1) describes a network-reachable, low-complexity flaw requiring only a low-privilege authenticated account and no user interaction - a plausible insider or post-compromise escalation path in multi-tenant/RBAC deployments of ManageEngine OpManager and Firewall Analyzer. Exploitation status is 'no public exploit identified at time of analysis': there is no CISA KEV listing, no POC reference (the only reference is the vendor advisory), and EPSS is not provided, so exploitation probability cannot be quantified. The one signal that looks inflated is C:H: the description states only that a low-privilege user can 'modify Change Management report schedule configurations for firewalls outside their assigned scope,' which is fundamentally an integrity/authorization defect (CWE-639 IDOR), not a bulk data-disclosure primitive - C:H is defensible only if altering the schedule causes out-of-scope firewall change-management reports to be delivered to the attacker (indirect disclosure). Absent active-exploitation or POC signals, this is a moderate-priority patch: real (broken tenant/scope isolation in a security appliance) but not an emergency, and best prioritized where OpManager/Firewall Analyzer is exposed to many low-trust users. |
| Exploit ScenarioDerived | A low-privilege authenticated user of ManageEngine OpManager or Firewall Analyzer sends a crafted request to the Change Management report-schedule endpoint referencing a firewall ID outside their assigned scope, and the server applies the change without an ownership/scope check. The attacker can thereby reconfigure or redirect scheduled change-management reporting for firewalls they should not administer. No public exploit code is identified at time of analysis; exploitation requires a valid low-privilege account. |

Alert meAnalysisAIv1 – Sep 23, 2026
Broken access control in ZohoCorp ManageEngine OpManager and Firewall Analyzer 12.8.710 and below allows an authenticated low-privilege user to modify Change Management report schedule configurations for firewalls outside their assigned scope. The vendor CVSS 3.1 vector is 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N), but independent assessment adjusts confidentiality to Low (C:L/I:L), because impact is limited to cross-scope report scheduling data and requires a pre-existing low-privilege account plus a multi-scope/RBAC deployment. No public exploit or CISA KEV listing was identified at time of analysis.
RemediationAI
Apply the vendor fix per the ManageEngine advisory at https://www.manageengine.com/itom/advisory/cve-2026-84791.html. The provided data identifies 12.8.710 and below as vulnerable but does not state an exact patched version, so treat it as patch available per vendor advisory and upgrade to the latest vendor-supported release above 12.8.710 as directed by that advisory. If immediate upgrade is not possible, restrict web-interface and Change Management report-scheduling access to trusted administrative networks or VPN, and audit/remove unnecessary low-privilege accounts and excessive firewall scope assignments; these measures shrink the attacker population and reachable cross-scope objects but do not fix the broken object-level authorization. Enable logging and review report-schedule changes for cross-scope modifications, and monitor the advisory for the exact fixed build.

Technical ContextAI · show details
Root cause is CWE-639 (Authorization Bypass Through User-Controlled Key): the web application accepts a user-controlled identifier or reference for a Change Management report schedule and fails to verify that the referenced firewall is within the authenticated user's assigned scope. CPE data identifies the affected products as cpe:2.3:a:zohocorp:manageengine_opmanager:*:*:*:*:*:*:*:* and cpe:2.3:a:zohocorp:manageengine_firewall_analyzer:*:*:*:*:*:*:*:*, with the description bounding affected builds to 12.8.710 and below. The assessed CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N (vendor lists C:H, independent assessment C:L) means the flaw is network-reachable, low complexity, requires a valid low-privilege authenticated account, and needs no user interaction. It is most relevant in multi-tenant or RBAC deployments that segment firewalls across scopes; single-scope or single-admin installations have little cross-scope data to manipulate. The supplied tag Authentication Bypass is imprecise here: the described behavior is broken object-level authorization, not a credential bypass.

Authenticated low-privilege network attacker (PR:L, AV:N, AC:L) modifies out-of-scope config; primary impact is integrity with limited confidentiality via leaked reports, so C:L/I:L rather than vendor's C:H.

Lifecycle Timeline
2DescriptionCVE.org
ZohoCorp ManageEngine OpManager and Firewall Analyzer versions 12.8.710 and below were vulnerable to a Broken Access Control vulnerability that allowed an authenticated low-privilege user to modify Change Management report schedule configurations for firewalls outside their assigned scope.
Executive ViewAI
ManageEngine OpManager and Firewall Analyzer 12.8.710 and below contain a broken access control flaw that lets authenticated low-privilege users in multi-scope RBAC deployments modify Change Management report schedules for firewalls outside their assigned scope. This can weaken firewall change governance, audit evidence, and operational reporting, though the confidentiality impact is limited to cross-scope scheduling data and no public exploit identified at time of analysis. Security and compliance leaders should care because these reports often support audit and change-control obligations, and no vendor-released patch identified at time of analysis.
Restrict authenticated low-privilege access in multi-scope/RBAC deployments, enforce least privilege, audit Change Management report schedules, segment firewall scopes, and monitor for cross-scope modifications until a vendor patch is released.
