IT Security and Insecurity Portal www.waraxe.us Forum Index -> Sql injection -> SQL Injection - Getting around addslashes()    View previous topic :: View next topic  SQL Injection - Getting around addslashes() Posted: Thu Aug 26, 2010 8:14 pm shadowplayer Beginner   Joined: Aug 26, 2010 Posts: 2 Hi guys =) I'm stuck with this injection, please help me with some ideas. The query is (watch quotes): Code: SELECT users.* FROM users WHERE true AND users.email = '{$email}' Setting email to %00 (null) consumes the last single-quote in the query. Problem: Single-quotes (only single ones) are escaped by addslashes() (maybe magic_quotes). I've tried with multibyte chars like this: Code: email=%C0%27%00 Not working either... I'm getting escaped quotes. Any ideas? Re: SQL Injection - Getting around addslashes() Posted: Fri Aug 27, 2010 3:42 pm shadowplayer Beginner   Joined: Aug 26, 2010 Posts: 2 bump*!

Posted: Mon Aug 30, 2010 11:19 am waraxe Site admin   Joined: May 11, 2004 Posts: 2399 Location: Estonia, Tartu If magic_quotes_gpc=on or if addslashes(), mysql_escape_string(), mysql_real_escape_string() is used for incoming data sanitization, then there is no sql injection. Sql injection occurs when (examples) : 1. magic_quotes_gpc=off (easy to exploit) 2. stripslashes() is used (easy to exploit) 3. urldecode() or rawurldecode() is used (easy to exploit) 4. magic_quotes_runtime=off (second order injection, specific cases, hard to exploit) 5. specific cases related to sql truncation (hard to exploit) By the way, when magic_quotes_gpc=on, then null byte (%00) trick will not work either, becasue it will be escaped too.
