The CVE-2025-XXXX vulnerability in Joomla’s Framework Database Package stems from improper sanitization in the `quoteNameStr` method, leading to SQL injection. This protected method mishandles identifier escaping, allowing attackers to inject malicious SQL queries if a derived class improperly uses it. While the core Joomla database class does not invoke this method directly, third-party extensions extending the vulnerable class may expose the flaw. Attackers can exploit this by crafting malicious input that bypasses escaping, manipulating database queries to extract or modify data.
DailyCVE Form:
Platform: Joomla Framework
Version: 1.0.0-2.2.0, 3.0.0-3.4.0
Vulnerability: SQL Injection
Severity: Moderate
Date: Apr 9, 2025
What Undercode Say:
Exploitation:
// Malicious input bypassing quoteNameStr $input = "admin' OR 1=1 --"; $db->quoteNameStr($input); // Executes unintended SQL
Detection:
-- Check logs for unusual queries SELECT FROM mysql.general_log WHERE argument LIKE '%quoteNameStr%';
Mitigation:
- Update to Joomla Database Package v2.2.0 or 3.4.0.
2. Audit custom extensions for `quoteNameStr` usage.
Patch Analysis:
- return "'" . str_replace("'", "''", $name) . "'";
+ return "'" . str_replace(array("'", "\0"), array("''", ""), $name) . "'";
Protection Commands:
Block suspicious requests iptables -A INPUT -p tcp --dport 80 -m string --string "quoteNameStr" --algo bm -j DROP
Vulnerable Code Example:
class CustomDB extends JDatabaseDriver {
public function unsafeQuery($input) {
return $this->quoteNameStr($input); // Exploitable
}
}
Secure Alternative:
// Use Joomla’s built-in escaping $db->quote($input);
Log Monitoring:
grep -r "quoteNameStr" /var/www/html/libraries/src/Database/
