In the first blog of this series, I introduced common SQL Injection attacks and defense technologies. This vulnerability can cause some very serious consequences, but fortunately we can prevent SQL Injection by limiting the permissions of user databases, using parameterized SQL statements, or using ORM and other technologies, next we will introduce you to Cross-site

attacks. Some rules are simple and extreme, and a potential attack will be vigilant. However, these extreme rules can lead to some active errors. With this in mind, we have modified these simple rules and used other styles to make them more accurate. In the attack detection of these network applications, we recommend that you use these as the starting point for debugging your IDS or log analysis methods. A

Alert (/xss/) will do an event execution, so even ubb tags become unsafe and can be spared "protection." Many forums do not pay attention to this, phpwind, such as the Dynamic Network forum is vulnerable to such attacks. Discuz fixes this security issue by appending a space after the result of the transformation. The use of the UBB tag here is actually a very interesti

In the past two years, security experts should pay more attention to attacks at the network application layer. No matter how strong firewall rule settings you have or how often you fix vulnerabilities, if your network application develo

There have been a lot of discussions on these two WEB-based attacks, such as how to launch attacks, their impact, and how to better compile and design programs to prevent these attacks. However, there is not enough discussion about how to detect these attacks. We use the popular open-source IDS Snort [ref 3] to construct a regular expression based on the rules used to detect these attacks

Eclipse is an open-source and Java-based scalable development platform. It is widely used in the world. This article describes how to exploit a cross-site scripting vulnerability on the local Eclipse Web server. More importantly, we will learn an advanced technique for dealing with space characters in a valid load.
