Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.40% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Icinga icingaweb2-module-director and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Distribution package intelligence

Release-specific package status

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

5 package states
Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

What, why and how

Icinga Director is an Icinga config deployment tool. A Security vulnerability has been found starting in version 1.0.0 and prior to 1.10.4 and 1.11.4 on several director endpoints of REST API. To reproduce this vulnerability an authenticated user with permission to access the Director is required (plus api access with regard to the api endpoints). And even though some of these Icinga Director users are restricted from accessing certain objects, are able to retrieve information related to them if their name is known. This makes it possible to change the configuration of these objects by those Icinga Director users restricted from accessing them. This results in further exploitation, data breaches and sensitive information disclosure. Affected endpoints include icingaweb2/director/service, if the host name is left out of the query; icingaweb2/directore/notification; icingaweb2/director/serviceset; and icingaweb2/director/scheduled-downtime. In addition, the endpoint `icingaweb2/director/services?host=filteredHostName` returns a status code 200 even though the services for the host is filtered. This in turn lets the restricted user know that the host `filteredHostName` exists even though the user is restricted from accessing it. This could again result in further exploitation of this information and data breaches. Icinga Director has patches in versions 1.10.4 and 1.11.4. If upgrading is not feasible, disable the director module for the users other than admin role for the time being.

Why

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may obtain information outside the intended access boundary.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Exposure of Sensitive Information to an Unauthorized Actor → obtain information outside the intended access boundary

CWE-200 ↗

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.ILowIntegrity impact: A successful attack can cause a limited loss.ANoneAvailability impact: No direct loss is represented by this metric.
Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
