Inyección de código

Errores de inyección

Estado de vulnerabilidad que se crea por métodos de codificación poco seguros, y que tiene como resultado una validación de entradas inapropiada, que permite a los atacantes transferir código malicioso al sistema subyacente a través de una aplicación web. En esta clase de vulnerabilidades se incluye la inyección SQL, la inyección LDAP y la inyección XPath.

(en) Injection Flaws

Vulnerability that is created from insecure coding techniques resulting in improper input validation, which allows attackers to relay malicious code through a web application to the underlying system. This class of vulnerabilities includes SQL injection, LDAP injection, and XPath injection.

(en) Code injection

This threat category includes well-known attack techniques against web applications such as SQL injection (SQLi), cross-site scripting (XSS), cross-site request forgery (CSRF), Remote File Inclusion (RFI) etc. The adversaries placing such attacks try to extract data, steal Responding to the Evolving Threat Environment credentials, take control of the targeted webserver or promote their malicious activities by exploiting vulnerabilities of web applications.

(en) CWE-94: Improper Control of Generation of Code ('Code Injection')

The software constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

When software allows a user's input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the software. Such an alteration could lead to arbitrary code execution.

Injection problems encompass a wide variety of issues -- all mitigated in very different ways. For this reason, the most effective way to discuss these weaknesses is to note the distinct features which classify them as injection weaknesses. The most important issue to note is that all injection problems share one thing in common -- i.e., they allow for the injection of control plane data into the user-controlled data plane. This means that the execution of the process may be altered by sending code in through legitimate data channels, using no other mechanism. While buffer overflows, and many other flaws, involve the use of some further issue to gain execution, injection problems need only for the data to be parsed. The most classic instantiations of this category of weakness are SQL injection and format string vulnerabilities.

(fr) Défauts d’injection

Vulnérabilité qui est créée par des techniques de codage non sécurisées, ce qui provoque la validation d’une entrée incorrecte qui permet aux pirates de relayer des codes malveillants par une application Web au système sous-jacent. Cette classe de vulnérabilité comprend les injections SQL, les injections LDAP et les injections XPath.
