• → Monitor HTTP requests targeting the Joomla! com_advertisementboard component with the task parameter set to 'show_rss_categories' and a non-empty or SQL-laden 'catname' parameter — this is the specific attack vector for CVE-2018-5982. ↗
• → Alert on URL query strings containing both 'option=com_advertisementboard' and 'task=show_rss_categories' alongside SQL metacharacters (quotes, SELECT, UNION, etc.) in the 'catname' parameter. ↗
• → The SQL injection payload uses an error-based technique leveraging INFORMATION_SCHEMA.PLUGINS with FLOOR(RAND(0)*2) to extract @@version and database() — tune WAF/IDS rules to detect this pattern in GET parameters. ↗

• · The exploit was tested specifically against Advertisement Board version 3.1.0; a prior vulnerability in v3.0.4 affecting the 'id' parameter is tracked separately (EDB-41600) and is distinct from CVE-2018-5982. ↗
