Joomla Extension - ordasoft.com - Reflected Cross-Site Scripting in Book Library (Free) < 6.4.6 - The public book-detail page template, site/views/viewbook/tmpl/default.php, echoes the raw title request parameter directly into a double-quoted HTML attribute with no escaping function of any kind (echo $REQUEST["title"];). A value containing a double quote closes the attribute early and allows arbitrary HTML/JavaScript to follow.

Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Book Library (Free) < 6.4.6 - site/booklibrary.php’s books() function reads the field and direction request parameters and passes each through a function called protectInjectionWithoutQuote(), whose only real protection is a keyword blacklist that, on detecting the literal substring select, wraps the value in $db->quote() instead of rejecting it. The value is then concatenated directly into an unquoted ORDER BY clause, a position where quoting provides no protection at all. Reaching the vulnerable code path requires two conditions: a first request to prime session-stored sort defaults, and a trailing decoy comment (-- xselect) that satisfies the blacklist’s substring check without altering the payload’s effect.
