- How Codeql analyzes the problem of cookie not enabling httponly
- Preface Today we use codeql to analyze security issues such as "cookie is not enabled httponly", thereby deepening our use of codeql. If the response is good, you can consider exploring other vulnerabilities in Vulnerability-goapp. When analyzing go programs, you must additionally download the codeql-go description audit object Vulnerability-goapp: VulnerablegolangWebapplicationforeducation. Modification: Because all cookies in this project are not set to http-only, there is no comparison, so we need to modify it first. in some cookies

- DeRPnStiNK target machine penetration case analysis
- DeRPnStiNK target machine penetration We found the DeRPnStiNK target machine from the Internet as an experimental environment. For beginners, we used this target machine to conduct penetration experiments. After downloading the target machine online, open it directly through the virtual machine. Just use the default bridge mode for the network card configuration. Note here that your kali attack machine must also be in bridge mode to ensure normal communication with the attacked server. First, if we are not sure about the address of the attacked server, we need to perform host discovery and check our own IP address: 192.168.50.76, as shown in the figure: Use nmap or netdiscover to perform network discovery. The command is as follows: nmap–sP192.168.50 .0/24(

- What is wide byte injection in SQL injection?
- Wide byte injection: It is a way to bypass SQL injection. 1. Wide byte concept: 1. Single-byte character set: all characters are represented by one byte, such as ASCII encoding (0-127) 2 . Multi-byte character set: In a multi-byte character set, some bytes are represented by multiple bytes, and another part (possibly none) is represented by a single byte. 3. UTF-8 encoding: It is an encoding method (multi-byte encoding). It can use 1 to 4 bytes to represent a symbol, and the byte length changes according to different symbols. 4. Common wide bytes: GB2312, GBK, GB18030, BIG5, Shift_JISGB2312 does not have wide byte injection, and it can be collected that there is wide byte injection

After all, this is significant for the development of Java deserialization vulnerabilities. Apache Commons Collections is a very commonly used tool library in Java application development. It adds many powerful data structures, simplifies the development of Java applications, and has become a recognized standard for Java to process collection data. Many common applications such as Weblogic, WebSphere, Jboss, Jenkins, etc. all use the Apache Commons Collections tool library. When a deserialization vulnerability occurs in the tool library, this

- Background With the development of the security industry, the country attaches great importance to it. Various industries suffer from various threats. Some companies of Party A do not have relevant security departments or have relatively weak security capabilities, so they will hire Party B's security personnel to provide operational services. Then Party B's security engineers need to help customers deal with some security events that occur during business operations. For example, after a vulnerability occurs, our security engineers need to detect whether other business systems have the vulnerability and whether it needs to be repaired in time. We also need to output some results to facilitate customer reporting, as well as how to improve work efficiency, etc. Review of common parameter options for efficient scanning Fast live scanning nmap-T4-n-V–sn-iLip.txt-oNlive_host.
