[NewAngels Advisory #7]PHP Nuke <= 7.8 Multiple SQL Injections ======================================================================== ===== Software: PHP Nuke 7.8 Type: SQL Injections Risk: High Date: Sep. 10 2005 Vendor: PHP-Nuke (phpnuke.org) Credit: ======= Robin 'onkel_fisch' Verton from it-security23.net Description: ============ PHP-Nuke is a news automated system specially designed to be used in Intranets and Internet. The Administrator has total control of his web site, registered users, and he will have in the hand a powerful assembly of tools to maintain an active and 100% interactive web site using databases. [http://www.phpnuke.org/] Vulnerability: ============== PHP Nuke 7.8 is prone to multiple SQL injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input before using it in SQL queries. In the modules.php $result = $db->sql_query("SELECT active, view FROM ".$prefix."_modules WHERE title='$name'"); The $name variable is not checked so you could inject malicious SQL Code. In an file which is included whe have the following code: $queryString = strtolower($_SERVER['QUERY_STRING']); if (stripos_clone($queryString,'%20union%20') OR stripos_clone($queryString,'/*') OR stripos_clone($queryString,'*/union/*') OR stripos_clone($queryString,'c2nyaxb0')) { header("Location: index.php"); die(); } [...] if (!ini_get("register_globals")) { import_request_variables('GPC'); } So you can use UNION in a GET var. But because they use register_globals or impor_request_variables you can send the malicous SQL-Code via POST so it is not checked if you insert an "union". http://www.example.com/modules.php POST: name=' OR 1=1/* will produce an error, neither http://www.example.com/modules.php POST: name=' OR 1=2/* will only tell you taht the requestet 'modul' is not active, so you can read out the admin password hahs via blind injections. Additionaly there are a few SQL-Injections in the modules. Here a few examples: http://www.example.com/modules.php?name=News&file=article&sid=[SQL] - here the same as above, send this via POST to bypass the 'union'-cover http://www.example.com/modules.php?name=News&file=comments&Reply&pid=[SQ L] http://www.example.com/modules.php?name=News&file=comments&op=Reply&pid= [SQL] http://www.example.com/modules.php?name=News&file=comments&op=Reply&sid= [SQL] Greets: ============== CyberDead, atomic, sirius_ Whole secured-pussy.de Team Zealots :D :D
