Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A non-admin user can change or remove important features within the Zabbix Agent application, thus impacting the integrity and availability of the application.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is an authorization vulnerability in Zabbix Agent where non-admin users can modify or remove critical application features, compromising system integrity and availability. The flaw allows unprivileged users to alter agent configurations or functionality that should be restricted to administrators.

MitigationImplement role-based access controls (RBAC) to ensure non-admin users cannot modify agent configurations or features; restrict elevated permissions to admin accounts only.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Zabbix Agent installation and version
    Run 'zabbix_agentd --version' or check package manager for Zabbix Agent version (e.g., 'dpkg -l zabbix-agent' or 'rpm -qi zabbix-agent')
    Affected if Installed version falls within 5.0.0-5.0.42, 6.0.0-6.0.30, 6.4.0-6.4.15, or is exactly 7.0.0
  2. Check Zabbix user role assignments
    Access Zabbix web frontend or query the users table in the Zabbix database to review role assignments for non-admin users
    Affected if Any non-administrator user account is assigned a role with permissions to modify agent configurations or critical features
  3. Inspect agent configuration file access controls
    Check file permissions on Zabbix Agent configuration files (e.g., zabbix_agentd.conf) using 'ls -la' - verify only root or zabbix user has write access
    Affected if Configuration files are writable by non-privileged users or groups outside the Zabbix service account
  4. Verify authorization controls for API/frontend actions
    Review Zabbix user group permissions and role definitions in the Zabbix database, specifically checking if 'write' or 'execute' permissions exist for 'scripts', 'actions', or 'conf' object types for non-admin users
    Affected if Non-admin users have been granted write permissions to scripts, actions, or configuration objects that control agent behavior

A user is affected if Zabbix Agent version is within the affected ranges AND non-administrator accounts have elevated permissions to modify agent configurations or critical system features.

Upgrade available Upgrade to a release after 6.4.15
Interim mitigation

Implement role-based access controls (RBAC) to ensure non-admin users cannot modify agent configurations or features; restrict elevated permissions to admin accounts only.

Recommended fix Moderate confidence

Zabbix 5.0.43+/6.0.31+/6.4.16+/7.0.1+ (depending on your major version branch)

  1. 1. Identify your current Zabbix version by checking the Zabbix Agent and Server package/version
  2. 2. For Zabbix 5.0.x: Upgrade to version 5.0.43 or later
  3. 3. For Zabbix 6.0.x: Upgrade to version 6.0.31 or later
  4. 4. For Zabbix 6.4.x: Upgrade to version 6.4.16 or later
  5. 5. For Zabbix 7.0.0: Upgrade to version 7.0.1 or later
  6. 6. After upgrading, verify that non-admin users can no longer modify or remove critical Zabbix Agent features
  7. 7. Test that the Zabbix Agent continues to function correctly with the upgraded version
