Name: Access Control Check Implemented After Asset is Accessed

A product's hardware-based access control check occurs after the asset has been accessed.

CWE Description

The product implements a hardware-based access control check. The asset should be accessible only after the check is successful. If, however, this operation is not atomic and the asset is accessed before the check is complete, the security of the system may be compromised.

Common Consequences

Scope Impact Likelihood
Access Control
Confidentiality
Integrity		Modify Memory, Read Memory, Modify Application Data, Read Application Data, Gain Privileges or Assume Identity, Bypass Protection Mechanism

Potential Mitigations

Phases : Implementation
Implement the access control check first. Access should only be given to asset if agent is authorized.

Vulnerability Mapping Notes

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Related Attack Patterns

CAPEC-ID Attack Pattern Name
CAPEC-180 Exploiting Incorrectly Configured Access Control Security Levels
An attacker exploits a weakness in the configuration of access controls and is able to bypass the intended protection that these measures guard against and thereby obtain unauthorized access to the system or network. Sensitive functionality should always be protected with access controls. However configuring all but the most trivial access control systems can be very complicated and there are many opportunities for mistakes. If an attacker can learn of incorrectly configured access security settings, they may be able to exploit this in an attack.
