Detalle CWE-259

The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound communication to external components.

Phases : Architecture and Design
For outbound authentication: store passwords outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible.
Phases : Architecture and Design
For inbound authentication: Rather than hard-code a default username and password for first time logins, utilize a "first login" mode that requires the user to enter a unique strong password.
Phases : Architecture and Design
Perform access control checks and limit which entities can access the feature that requires the hard-coded password. For example, a feature might only be enabled through the system console instead of through a network connection.

Métodos de detección

Manual Analysis

This weakness can be detected using tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session.

Black Box

Automated Static Analysis

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.)

Notas de mapeo de vulnerabilidades

Justificación : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comentario : 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.

Notas

It might be appropriate to split this entry into an inbound variant and an outbound variant. These variants are likely to have different consequences, detectability, etc., although such differences are not suitable for a split. More importantly, from a vulnerability theory perspective, they might be characterized as different behaviors. The difference is in where the hard-coded password is stored - on the component performing the authentication, or the component that is connecting to the external component that requires authentication. However, as with many weaknesses, the "vulnerability topology" should not be regarded as important enough for splits. For example, separate weaknesses do not exist for client-to-server buffer overflows versus server-to-client buffer overflows.
