Evidence used

  • No CISA KEV confirmation is currently recorded.
  • A structured source references public exploit or proof-of-concept material.
  • EPSS is 0.91% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs zlt2000 microservices-platform 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: Within 3 daysRemediation target: Within 90 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.

No EUVD known-exploited evidence

zlt2000 microservices-platform through 6.0.0 contains a missing authorization vulnerability where the zlt.security.auth.urlPermission.enable flag defaults to false, disabling all permission checks after authentication. Authenticated users with no roles can access administrative APIs including user management, role assignment, and Elasticsearch index operations by bypassing the disabled authorization enforcement.

01

What, why and how

zlt2000 microservices-platform through 6.0.0 contains a missing authorization vulnerability where the zlt.security.auth.urlPermission.enable flag defaults to false, disabling all permission checks after authentication. Authenticated users with no roles can access administrative APIs including user management, role assignment, and Elasticsearch index operations by bypassing the disabled authorization enforcement.

What

zlt2000 microservices-platform through 6.0.0 contains a missing authorization vulnerability where the zlt.security.auth.urlPermission.enable flag defaults to false, disabling all permission checks after authentication. Authenticated users with no roles can access administrative APIs including user management, role assignment, and Elasticsearch index operations by bypassing the disabled authorization enforcement.

Why

The application reaches a protected operation without first confirming that the requester is authorised.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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.
Reference recorded

CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.
