Incorrect Block Delimitation

Description

The code does not explicitly delimit a block that is intended to contain 2 or more statements, creating a logic error.

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.

Common Consequences

Scope: Confidentiality, Integrity, Availability

Impact: Alter Execution Logic

Notes: 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.
