CWE-483 — Incorrect Block Delimitation
CWE-483: Incorrect Block Delimitation
MITRE CWE weakness
| Kind | Weakness |
| Abstraction | Base |
| Status | Draft |
| Likelihood of exploit | Low |
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
- Confidentiality, Integrity, Availability: Alter Execution Logic
Mitigations
Implementation — Always use explicit block delimitation and use static-analysis technologies to enforce this practice.
