Summary
generated automatically from NVD dataThe Book Library (Free) extension for Joomla by ordasoft.com, in versions before 6.4.6, has an unauthenticated SQL injection (CWE-89) in the books() function of site/booklibrary.php. The field and direction request parameters pass through protectInjectionWithoutQuote(), a keyword blacklist that merely quotes values containing "select", and the result is concatenated into an unquoted ORDER BY clause where quoting offers no protection. Exploitation requires a priming request to set session sort defaults plus a trailing decoy comment, and the flaw is rated CVSS 9.8 (CRITICAL).
NVD description
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.
