What is the command injection?

command injection is the use of weakness of the system that will access the system to carry out malicious code, harvest user data and engage in other activities. Although there is a potential for injection of the command to be benign in nature, it is usually not and can represent a significant security threat. There are a number of solutions designed to prevent this activity in computer systems. The forms allow people to enter data and are then processed by the system. If there are no data restrictions entered in the form, it is possible for people to insert a computer code that the system reads and performs. The forms on the website can also convert the input to display other users and expose other people to the code; For example, someone could leave a harmful script in the comments on the website, can do things like providing people with access to the backend of a computer system, including an administrative approach, and can also plant viruses and malware to conceiveAny system. Command injection can be designed to spread because infected computers interact with uninfected computers via the network. They can spread very quickly and can cause considerable damage along the way.

One way to avoid injection of the command is to design forms and other inputs designed to limit what people can enter. For example, on Internet comments, there would probably be no legitimate reason why users would enter scripts and a comment form could simply refuse a script, still allowing HTML for marking and styling. Likewise, in the computer program, the input forms could refuse inputs of certain characters, which prevented people from implementing the code in the form.

The potential risk of presching the command was first recorded at the age of 90. Numerous designers solved the problem and came up with different ways to prevent nobo stop command attacks. Hackers have also tried to develop their own solutions and develop new and creative ways to carry out code through weak points in the computer system. Some people develop new techniques from purely academic interest and occasionally cause confusion by accident when their research escapes into the countryside to say.
