Waf xss bypass posture
Due to the wide use of application firewalls, it is necessary to test WAF's ability to defend against xss attacks. Of course, all the experiments are to prove that the vendor must eliminate the vulnerability from the root cause, and cannot lie on the WAF without any worries.Some popular WAF such as F5 Big IP, Imperva Incapsula, AQTRONIX Web

I. About SQL injectionSQL injection is a common technique for invading Web applications. SQL injection is a result of changing the original SQL statement execution logic using the application system's programming vulnerability and the syntax characteristics of the SQL language.An attacker sends carefully constructed input data to a Web application that is interpreted as a SQL instruction, alters the original normal SQL execution logic, executes an attacker-issued SQL command, This ultimately all

Most common and easy-to-deploy application tier classes (before Apache, after Apache)The application layer waf– leverages the WAF's own flaws and MySQL syntax features and combines the actual bypass:WAF most common detection method: keyword Detection For example, if a [space]union[space] Such an SQL statement is considered a malicious request, discard this packet,
WAF Defense Capability Evaluation and tools
This article describes how to evaluate a WAF from the defense capability of conventional attacks. A total of 16 attack types are covered, each of which ranges from the Use scenario (The purpose of the attack operation) to the injection point (where the vulnerability is generated, for example, most WAF comprehensively c

1, HPP http parameter Pollution http parameter pollution means that the server side usually does some processing when submitting two parameters of the same key value in the URL. For example, Apache is going to take the last argument, for example: user.php?id=111id=222 If you output a $_get array, the ID's value will only take 222, i.e. the extra value submitted on the URL overrides the previous value.

Who is the best choice?
Web application protection is undoubtedly a hot topic. Because of the maturity of technologies and the increasing expectation of convenience, Web applications have become the mainstream carrier of business systems. The data value contained in the key business systems of "anjia" on the Web has aroused the favor of attackers. The Web vulnerability mining and attack tools circulating on the Internet have lowered the attack threshold, it also makes many attacks blind and rand

Because MSSQL supports multi-statement injection, hackers can use a combined SQL statement to automatically tamper with the field content of the entire database and perform webpage Trojan attacks without any difference on the website.
