REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Risk

Başarılı sömürü neye yol açar?

Gain Privileges or Assume IdentityModify Application DataExecute Unauthorized Code or Commands

Etkilenen güvenlik alanları: Access Control, Integrity, Confidentiality

An attacker could gain access to sensitive data and possibly execute unauthorized code.

Savunma

Nasıl önlenir ve çözülür?

  • Follow secure coding guidelines for input handling and boundary checking.
  • Enforce strict security reviews and automated static analysis (SAST) checks.

Doğrulama

Nasıl tespit edilir?

Automated Static Analysis

High
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
