Hiện thực hóa: REALIZATION: This weakness is caused during implementation of an architectural security tactic.
Hiện thực hóa: This issue is frequently found in PHP applications that allow users to set configuration variables that are stored within executable PHP files. Technically, this could also be performed in some compiled code (e.g., by byte-patching an executable), although it is highly unlikely.

Tác động	Phạm vi	Diễn giải
Đọc tệp hoặc thư mục, Đọc dữ liệu ứng dụng	Tính bí mật	The injected code could access restricted data / files.
Vượt qua cơ chế bảo vệ	Kiểm soát truy cập	In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Chiếm đặc quyền hoặc mạo danh	Kiểm soát truy cập	Injected code can access resources that the attacker is directly prevented from accessing.
Thực thi mã hoặc lệnh trái phép	Tính toàn vẹn, Tính bí mật, Tính sẵn sàng, Khác	Code injection attacks can lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing. Additionally, code injection can often result in the execution of arbitrary code.
Che giấu hoạt động	Chống chối bỏ	Often the actions performed by injected control code are unlogged.

Kiểm tra dữ liệu đầu vào · Hiện thực hóaAssume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does. When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue." Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
Mã hóa ký tự đầu ra · Hiện thực hóaPerform proper output validation and escaping to neutralize all code syntax from data written to code files.

Phương pháp	Cách làm	Hiệu quả
Phân tích tĩnh tự động	Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)	-
