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 contact groups configuration page. 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-18541.

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

SQL injection vulnerability in Centreon's contact groups configuration page allows authenticated remote attackers to inject malicious SQL queries via unsanitized user input. Successful exploitation enables privilege escalation to administrator level.

MitigationApply Centreon security patches for CVE-2022-42427; until patched, restrict access to the contact groups configuration page to trusted administrators only and monitor for suspicious SQL-like activity.

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
    Check the Centreon version by viewing the file /usr/share/centreon/.env or accessing Administration > About in the web interface
    Affected if version is below 21.10.11, or between 22.04.0 and 22.04.6 inclusive
  2. Confirm contact groups module access
    Navigate to Configuration > Users > Contact Groups in the Centreon web interface, or check if the contactgroup menu is enabled in the user menu configuration
    Affected if the contact groups configuration page is accessible to the authenticated user
  3. Verify database user privileges
    Check the MySQL/MariaDB user that Centreon uses by reviewing /etc/centreon/conf.php or the database connection configuration; run: SELECT user, host FROM mysql.user WHERE db='centreon';
    Affected if the Centreon database user has elevated privileges that could allow privilege escalation through successful SQL injection
  4. Review Centreon access logs for SQL injection patterns
    Examine web server access logs (typically /var/log/nginx/access.log or /var/log/apache2/access.log) for unusual SQL syntax in requests to contactgroup or contact groups related endpoints
    Affected if log entries show SQL keywords (UNION, SELECT, INSERT, --) in parameters related to contact group configuration requests

user is affected if Centreon version is below 21.10.11 or between 22.04.0 and 22.04.6 AND they have authenticated access to the contact groups configuration page

Interim mitigation

Apply Centreon security patches for CVE-2022-42427; until patched, restrict access to the contact groups configuration page to trusted administrators only and monitor for suspicious SQL-like activity.

Recommended fix High confidence

Centreon 21.10.11 or Centreon 22.04.6 (or latest stable release in your respective branch)

  1. Identify your current Centreon version by checking the 'Administration' > 'Parameters' > 'About' page
  2. If using Centreon 21.10.x (versions < 21.10.11): Upgrade to Centreon 21.10.11 or later stable release
  3. If using Centreon 22.04.x (versions >= 22.04.0 and < 22.04.6): Upgrade to Centreon 22.04.6 or later stable release
  4. After upgrade, verify the contact groups configuration page functions correctly at: Configuration > Users > Contact Groups
  5. Test that SQL injection is no longer possible in the contact groups form fields
Caveat Review Centreon upgrade documentation for your version path as database migrations may be required; test in non-production environment first
