Risk

What does successful exploitation lead to?

Read Application DataGain Privileges or Assume IdentityExecute Unauthorized Code or Commands

Affected security scopes: Integrity, Confidentiality, Availability, Access Control

This weakness can lead to the exposure of resources or functionality to unintended actors, possibly providing attackers with sensitive information or even execute arbitrary code.

Defence

How is it prevented and fixed?

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