CWE-863Incorrect Authorization

Description

The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.

Common consequences

• Confidentiality→Read Application Data,Read Files or Directories
  An attacker could bypass intended access restrictions to read sensitive data, either by reading the data directly from a data store that is not correctly restricted, or by accessing insufficiently-protected, privileged functionality to read
• Integrity→Modify Application Data,Modify Files or Directories
  An attacker could bypass intended access restrictions to modify sensitive data, either by writing the data directly to a data store that is not correctly restricted, or by accessing insufficiently-protected, privileged functionality to writ
• Access Control→Gain Privileges or Assume Identity,Bypass Protection Mechanism
  An attacker could bypass intended access restrictions to gain privileges by modifying or reading critical data directly, or by accessing privileged functionality.
• Confidentiality,Integrity,Availability→Execute Unauthorized Code or Commands
  An attacker could use elevated privileges to execute unauthorized commands or code.
• Availability→DoS: Crash, Exit, or Restart,DoS: Resource Consumption (CPU),DoS: Resource Consumption (Memory),DoS: Resource Consumptio
  An attacker could gain unauthorized access to resources on the system and excessively consume those resources, leading to a denial of service.

Potential mitigations

• Architecture and Design
  [object Object]
• Architecture and Design
  Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible

• System Configuration,Installation
  Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
