Description
The software contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data.
Modes of Introduction:
– Architecture and Design
Likelihood of Exploit: High

CWE-287
CWE-287
CWE-344
CWE-671
CWE-257
Consequences
Access Control: Bypass Protection Mechanism
If hard-coded passwords are used, it is almost certain that malicious users will gain access to the account in question.
Integrity, Confidentiality, Availability, Access Control, Other: Read Application Data, Gain Privileges or Assume Identity, Execute Unauthorized Code or Commands, Other
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.

Description:
For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a “first login” mode that requires the user to enter a unique strong password or key.
Phase: Architecture and Design
Effectiveness:
Description:
If the software must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.
