sql-injection

I'm having a problem using $wbdb. When I insert or update data using $wpdb->insert or $wpdb->update, the SQL injection protection actually inserts the \' into the database, and when outputting that information it has the SQL escape with it. (ie: My Value\'s Escaped). I know there's gotta be a way to escape this using a wordpress function, but I haven't been able to find it searching google and the wordpress codex. ...So what's that function, or what am I doing wrong (seems like the '\' shouldn't really get to the database in the first place) Thanks! jason It looks as if magic_quotes are

I'm currently writing an application which uses ajax on the front end and ASP.NET (C#) on the back end.. A Small Part of the application does an AJAX call to the backend code (to get entries from the SQL database) How can i prevent SQL of JScript injection? I know it is generally unsecure to validate with javascript because javascript can be turned off but as this is an AJAX call so if the user has javascript turned off the AJAX will never run. Whats the best way of validating or escaping the input? Like Add_Slashes() in PHP? Thanks Daniel Use parametrized queries, never build SQL code strings

Problem: I have a form with text values, and a function that must return a string query based on the values of the text values too. Solution: I created a SQLCommand query with parameters, then I put the SQLCommand.CommandText to a string and I returned it (to the business logic that is going to handle the query) Main Question: Is it sql-injection proof? Code Example: sQuery = "select * from xy where x like '%@txtNameParameter%'"; SqlCommand cmd = new SqlCommand(sQuery); cmd.Parameters.Add("@txtNameParameter", SqlDbType.VarChar); cmd.Parameters["@txtNameParameter"].Value = txtName.Text; string

Couldn't seem to find a answer but wondering if the following query to the database is vulnerable to sql injection. $searchPostResults = $wpdb->get_results($querySearchVals, OBJECT); This is the query which is used: global $wpdb; $offset = (isset($_POST["moreSearchResults"])) ? $_POST["searchOffset"] : 0; $querySearchVals = " SELECT DISTINCT post_title, ID FROM {$wpdb->prefix}posts WHERE ("; $sVals = array(); $sVals = explode(" ", $searchVal); $lastIndex = intval(count($sVals)) - 1; $orderByCaseVals = ""; for($i = 0; $i<count($sVals);$i++) { $querySearchVals .= " post_title LIKE '%$sVals[$i]%'

I have the following code in my btn_click event: Sqlconnection con = new Sqlconnection("server=.;database=bss;user id=ab;pwd=ab"); con.open(); SqlCommand cmd = new Sqlcommand("select * from login where username='" + txt4name.Text + "' and pwd='" + txt4pwd.Text + "'", con); SqlDataReader reader = cmd.execute Reader(); Where login is the table and username and pwd are its fields. After this code all the values are stored in the reader object. I want to store username and pwd in the separate variables. How can I accomplish this? In general, when accessing your DB, you should be using something

I was reading last night on preventing SQL injections, and I ran across this answer: How can I prevent SQL injection in PHP? The comments from 'Your Common Sense' made it sound like that was dysfunctional/unsafe. However, in my (albeit limited) testing, I found that php's "bin2hex($var)" worked with anything I threw at it - literal number, number string, string of text - even when matching a numerical (tinyint) column. My question is this: Is there a way to inject SQL when every user input is sanitized via hexing it? In essence, any time a query was made, it would look something like this:

Is it possible for a project using entirely LinqToSQL or Entity Framewok to suffer from SQL Injection. I think that probably not because the SQL that the ORM generates should be sql-injection free. But I'm not sure. When you use those frameworks as intended, i.e. the entities/tables directly, then no. All string comparisons (i.e. where name = 'smith' ) are parameterized. The only vulnerable spots are: any string can be executed directly against the context. dbContext.ExecuteQuery(); with any kind of destructive string. a stored procedure executing dynamic SQL using any parameters given "It
