CWE-483: Incorrect Block Delimitation
The code does not explicitly delimit a block that is intended to contain 2 or more statements, creating a logic error.
How it's found
Incorrect Block Delimitation is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
In some languages, braces (or other delimiters) are optional for blocks. When the delimiter is omitted, it is possible to insert a logic error in which a statement is thought to be in a block but is not. In some cases, the logic error can have security implications.
Consequences
- Alter Execution Logic: This is a general logic error which will often lead to obviously-incorrect behaviors that are quickly noticed and fixed. In lightly tested or untested code, this error may be introduced it into a production environment and provide additional attack vectors by creating a control flow path leading to an unexpected state in the application. The consequences will depend on the types of behaviors that are being incorrectly executed.
Mitigations
- Implementation: Always use explicit block delimitation and use static-analysis technologies to enforce this practice.
