Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

常见后果
范围：Confidentiality
影响：Read Application Data
注释：Many injection attacks involve the disclosure of important information -- in terms of both data sensitivity and usefulness in further exploitation.
范围：Access Control
影响：Bypass Protection Mechanism
注释：In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
范围：Other
影响：Alter Execution Logic
注释：Injection attacks are characterized by the ability to significantly change the flow of a given process, and in some cases, to the execution of arbitrary code.
范围：Integrity, Other
影响：Other
注释：Data injection attacks lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing.
范围：Non-Repudiation
影响：Hide Activities
注释：Often the actions performed by injected control code are unlogged.
