Insufficient Encapsulation

Opis

The product does not sufficiently hide the internal representation and implementation details of data or methods, which might allow external components or modules to modify data unexpectedly, invoke unexpected functionality, or introduce dependencies that the programmer did not intend.

Skutki

• Access Control

  Varies by Context; Bypass Protection Mechanism

  An attacker can access data or methods that were not intended to be accessible.

• Other

  Reduce Maintainability; Increase Analytical Complexity

  This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
