This article is a short story about PHP serialization/object Injection Vulnerability Analysis, which describes how to get a remote shell for a host. If you want to test this vulnerability yourself, you can do so through XVWA and Kevgir. The first step in exploiting the exploits, we begin to test whether the target application has PHP
Simply put, the state of various objects stored in the memory can be read again. Although you can use your own methods to save object states, Java provides you with a mechanism better than your own to save the object state, that is, serialization.2. Under what circumstances
code, it is the embarrassment that needs to be almost repeated, which is really painful. To put it bluntly, the reason is that the program we originally wrote is not easy to maintain, has poor flexibility, and is not easy to expand, not to mention reuse. Therefore, in the f
For an object that exists in a Java virtual machine, its internal state remains in memory only. After the JVM has stopped, these states are lost. In many cases, the internal state of an object needs to be persisted. When it comes to persistence, the most straightforward approach is to save it to a file system or database. This approach typically involves custom s

There's no such thing as a "JSON object" By"Cowboy" Ben AlmanOn March 3, 2010 pm | 15 comments and 0 Reactions I want to clear up a common misconception. it's my belief that developers mistakenly call JavaScript Object literals "JSON objects" because their syntax is identical to (well, a superset of) what
Object serialization mainly solves the problem of saving the object state. The "object state" mentioned here refers to the set of Field Values owned by the object at a certain time point. The main functions of serialization are:
Note: I/O Stream-Object serialization and serialization The Java language supports a very general mechanism called ObjectSerialization, which can write any object to the stream and read it back later, first, classes that support object s

C ++ starts from scratch (12) -- What Is Object-Oriented Programming The most important concept of C ++-class has been described above, and most of the class-related knowledge has been introduced. So far, we can start to do some advanced programming applications-designing programs, instead of simply turning algorithms into code. To illustrate how to design a pr
