• → Detect SQL injection attempts against the CW Tags Joomla component by monitoring HTTP requests containing the array-style parameter 'searchtext[]' with the query string 'option=com_cwtags' ↗
• → The first payload (URL-decoded) injects: -Efe') /*!03333UNION*/ /*!03333SELECT*/ @@HOSTNAME-- - — look for inline comment obfuscation (/*!NNNNN...*/) combined with UNION SELECT in the searchtext[] parameter ↗
• → The second payload (URL-decoded) performs a time/error-based blind SQLi enumerating information_schema.tables — alert on requests to index.php?option=com_cwtags where searchtext[] contains references to 'information_schema' or 'concat(cast(database()' patterns ↗

• · The exploit PoC uses 'localhost' as the target host — replace with the actual target hostname/IP when operationalizing detection rules or scanning ↗
