• → Monitor HTTP requests targeting the Joomla component com_abook with the 'letter' GET parameter for SQL injection payloads (e.g., presence of SQL keywords, EXTRACTVALUE, CONCAT, or percent-encoded SQL syntax). ↗
• → Flag requests matching the pattern: option=com_abook&view=category&letter= with any non-alphabetic or encoded characters in the letter parameter value, as the injection point is the unsanitised 'letter' query parameter. ↗

• · The exploit was tested against version 3.1.2 beta specifically; other versions of the component may or may not be affected. ↗
