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
Insufficient sanitization of SQL queries in the `sqloptimizer` utility script allows SQL Injections on behalf of the root user if Slow Query logging is enabled.

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

The `sqloptimizer` utility script contains insufficient sanitization of SQL query inputs, allowing unauthenticated attackers to inject malicious SQL commands. Successful exploitation requires Slow Query logging to be enabled on the target database system, and results in SQL injection execution with root user privileges.

MitigationDisable Slow Query logging if not operationally required, or apply a vendor patch to the `sqloptimizer` script to implement proper input sanitization and parameterized queries.

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. Locate the sqloptimizer script
    Search for the sqloptimizer utility script in system directories using: find / -name 'sqloptimizer*' 2>/dev/null or check common utility paths
    Affected if The sqloptimizer script is present on the system
  2. Check if Slow Query logging is enabled
    Query the database configuration for slow_query_log status. For MySQL: SHOW GLOBAL VARIABLES LIKE 'slow_query_log'; For PostgreSQL: show log_min_duration_statement; Or review database config files (my.cnf, postgresql.conf)
    Affected if Slow Query logging is enabled on the target database system
  3. Examine script for SQL input handling
    Review the sqloptimizer script source code for how it processes SQL query inputs. Look for direct string concatenation, unsanitized variables passed to SQL queries, or lack of parameterized query implementation
    Affected if The script contains unsanitized SQL input parameters or uses string concatenation without input validation

Environment is affected if the sqloptimizer script exists, Slow Query logging is enabled, and the script contains unsanitized SQL input handling

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Disable Slow Query logging if not operationally required, or apply a vendor patch to the `sqloptimizer` script to implement proper input sanitization and parameterized queries.
