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
cPanel before 67.9999.103 allows SQL injection during eximstats processing (SEC-276).

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

SQL injection vulnerability in cPanel's eximstats processing component allows attackers to inject malicious SQL queries. Eximstats parses Exim mail server logs and generates statistics; the vulnerability exists in versions before 67.9999.103 and can be exploited without authentication.

MitigationUpgrade cPanel to version 67.9999.103 or later to patch the SQL injection vulnerability in eximstats processing.

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. Verify cPanel installation exists
    Check for cPanel directories or version file: ls -la /usr/local/cpanel/ or cat /usr/local/cpanel/version
    Affected if If the directory or version file does not exist, cPanel is not installed and this CVE does not apply
  2. Retrieve installed cPanel version
    Run: cat /usr/local/cpanel/version or whmapi1 get_cpanel_version
    Affected if The command returns a version number that falls within any of these ranges: 63.9999.74 to 64.0.39, 65.9999.38 to 66.0.22, or 67.9999.64 to 67.9999.102
  3. Confirm eximstats component is enabled
    Check if eximstats service is running: systemctl status eximstats or service eximstats status
    Affected if If eximstats is actively running, the vulnerable code path is present in the environment
  4. Check eximstats database existence
    Inspect /var/cpanel/eximstats/ directory or check for eximstats MySQL database: mysql -e 'SHOW DATABASES LIKE "eximstats";'
    Affected if If the eximstats database exists and contains parsed mail log data, the vulnerable parsing logic is in use

A user is affected if cPanel is installed with a version matching any of the three affected ranges AND the eximstats component is enabled and processing Exim mail logs.
