Vulnerability from emb3d
Type
Description
Hardcoded credentials typically cannot be changed by end-users and are often undocumented, leaving the end-user unaware of the risk. If a threat actor is able to discover the credentials for a device (or family of devices with the same password), they may be able to exploit multiple devices with no known device-level mitigation. Hardcoded credentials are often intended for vendor-specific diagnostic functions or to authenticate components designed to communicate together (e.g., a PLC and associated IED), but can be abused by threat actors when discovered. Often hardcoded credentials are added to support debugging during a device’s development and are mistakenly left in production devices.
