    Analysing Server Response and Page Source

    Posted in Anomalies

    Subtle impacts of SQL injection attacks on response. It is not always easy to tell if an inbound SQL injection test is positive or negative. Sometimes, a slight difference in the server response can indicate the attacker is on the right way. By carefully analysing the source code...

    SQL Injection Inference Attacks

    Posted in SQL Injection Techniques

    Understanding the fundamentals inference attacks. Inference technique is the pillar of blind SQL injection and it is used in many advanced attacks. It allows testing for vulnerabilities and even extract information when no data is returned to the end user. Moreover, mastering its fundamentals will...

    Extracting Information from Custom Errors

    Posted in Anomalies

    Understanding information provided by application errors. Software developers often use error handling and validation mechanisms to prevent the application from crashing when an unexpected event occurs. In those situations custom errors are habitually returned to the user to indicate that something wrong happened (without providing full...

    Detecting SQL Injection Vulnerabilities from HTTP Errors

    Posted in Anomalies

    Understanding HTTP errors generated by SQL injection attacks. While testing for SQL injection vulnerabilities or attempting to take over a query, the attacker may face different HTTP status codes. Those responses may indicate that the SQL injection partially worked and therefore give precious hints to the tester. This...

    SQL Injection and Database Errors

    Posted in Anomalies

    Understand and identify database errors. Information leaked by errors, especially database errors, can help an attacker to achieve a successful SQL injection attack. They basically give hints to help crafting an SQL segment that will be correcly integrated in the query. It can also reveal...

    SQL Injection Detection

    Posted in SQL Injection Test

    Detect potential SQL injection vulnerabilities. The first step towards achieving a successful SQL injection attack is to detect vulnerabilities. Of course, some tools can automate the process, but it’s better to understand how detection can be done manually. In addition, there are some situations where...
