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
This vulnerability allows remote attackers to escalate privileges on affected installations of Centreon. Authentication is required to exploit this vulnerability. The specific flaw exists within the handling of requests to modify poller broker configuration. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to escalate privileges to the level of an administrator. Was ZDI-CAN-18557.

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 · high confidence

This is a SQL injection vulnerability in Centreon's poller broker configuration module. An authenticated attacker can exploit improper input validation of user-supplied strings before they are used in SQL query construction, allowing privilege escalation to administrator level.

MitigationApply vendor-supplied patch for CVE-2022-42429. If no patch available, implement strict input validation and convert all database queries to parameterized statements to eliminate SQL injection vectors.

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 Centreon version
    Log into the Centreon web interface and navigate to Administration > Parameters > About, or check the installed package version using the command: cat /usr/share/centreon/version.txt or rpm -q centreon
    Affected if The installed version falls within these vulnerable ranges: < 21.04.19, >= 21.10.0 and < 21.10.11, or >= 22.04.0 and < 22.04.6
  2. Confirm poller broker configuration module access
    Navigate to Configuration > Pollers > Broker Configuration in the Centreon web interface. Verify this module is visible and accessible to your user account
    Affected if The poller broker configuration module is present and accessible without being explicitly disabled
  3. Verify authentication is enabled
    Check that Centreon user authentication is active by attempting to log in or reviewing the authentication configuration in Administration > Authentication > Authentication sources
    Affected if Centreon authentication is enabled, which is the default configuration and required for exploitation
  4. Check for unauthorized administrator accounts
    Review user accounts in Administration > Users > Contacts/Users and check for any unexpected administrator-level accounts that may indicate prior exploitation
    Affected if New or unrecognized administrator accounts exist that were not created by your organization

You are affected if your Centreon version is within the vulnerable ranges AND the poller broker configuration module is accessible to authenticated users.

Fixed in 21.04.1921.10.1122.04.6
Interim mitigation

Apply vendor-supplied patch for CVE-2022-42429. If no patch available, implement strict input validation and convert all database queries to parameterized statements to eliminate SQL injection vectors.

Recommended fix High confidence

21.04.19 or later (21.04.x line), 21.10.11 or later (21.10.x line), or 22.04.6 or later (22.04.x line)

  1. 1. Identify the currently installed Centreon version by checking the 'Administration' > 'Parameters' > 'About' page in the Centreon web interface
  2. 2. Based on your current version branch, plan an upgrade to the minimum fixed version: If using 21.04.x, upgrade to 21.04.19 or later; If using 21.10.x, upgrade to 21.10.11 or later; If using 22.04.x, upgrade to 22.04.6 or later
  3. 3. Before upgrading, perform a complete backup of the Centreon database using command: `mysqldump -u centreon -p centreon > centreon_backup_$(date +%Y%m%d).sql`
  4. 4. Before upgrading, back up the Centreon configuration files in /etc/centreon/ and /etc/httpd/conf.d/
  5. 5. Follow the official Centreon upgrade documentation for your distribution to install the target version
  6. 6. After upgrade, verify the Centreon web interface is functional and check that the version displayed matches the expected fixed version
  7. 7. Test that authenticated users can no longer exploit the poller broker configuration to perform SQL injection attacks
Caveat Standard Centreon upgrade may require PHP version compatibility and configuration file updates; test in non-production environment first
