The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
Many protocols and products have their own custom command language. While OS or shell command strings are frequently discovered and targeted, developers may not realize that these other command languages might also be vulnerable to attacks.
Modes of Introduction
Phase | Note |
---|---|
Implementation | Command injection vulnerabilities typically occur when: Data enters the application from an untrusted source. The data is part of a string that is executed as a command by the application. |
Implementation | REALIZATION: This weakness is caused during implementation of an architectural security tactic. |
