What is OS command injection?

Command injections (a.k.a. cmd injections) are among the most common types of attacks on the internet. This is due to the nature of web applications, which makes it possible to have many entry points where malicious commands can be injected.

Forms with unvalidated entry facilitate entering “extra” commands, which are integrated into the default command that is executed by the operating system (OS). Furthermore, certain types of functions, like system() and exec(), use the environment of the program that calls them. Attackers can take advantage of this functionality and influence the behavior of these calls. 

Command injection is different from code injection, as the latter allows attackers to add code that is executed by the application. Command injection, instead, extends the functionality of the application executing system commands. An attacker does not need to inject code at all. 

The consequences of a command injection attack can be potentially devastating. An attacker could:

  • Execute arbitrary commands with elevated privileges
  • Access data and manipulate it or delete it
  • Break the application or website
  • Compromise the hosting infrastructure
  • Gain access to other systems within the organization.

How Can You Prevent Command Injection Attacks? 

Command injection attacks are common. Fortunately, there are several strategies available to defend against them.

 

sql injection

Validate user input

Validate user input as close to the external interface as possible, to ensure that entered data contains only expected inputs. 

suppress data base messages

Review used languages

Java, PHP, Asp.Net, and Python are less susceptible to command injection because there is a framework between the application and the operating system.

sql injection

Avoid calling OS commands directly

Built-in library functions are a very good alternative to OS commands, and they cannot be manipulated to perform tasks other than those intended.
