CWE-413: Improper Resource Locking

MITRE CWE weakness

Description

The product does not lock or does not correctly lock a resource when the product must have exclusive access to the resource.

When a resource is not properly locked, an attacker could modify the resource while it is being operated on by the product. This might violate the product's assumption that the resource will not change, potentially leading to unexpected behaviors.

Common consequences

• Integrity, Availability: Modify Application Data, DoS: Instability, DoS: Crash, Exit, or Restart

Mitigations

Architecture and Design — Use a non-conflicting privilege scheme.

Architecture and Design — Use synchronization when locking a resource.
