CWE-201Insertion of Sensitive Information Into Sent Data

Description

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.

Common consequences

• Confidentiality→Read Files or Directories,Read Memory,Read Application Data
  Sensitive data may be exposed to attackers.

Potential mitigations

• Requirements
  Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data.
• Implementation
  Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere. Any information that is not necessary to the functionality should be removed in order to lower both the overhead and the possibility of security sensitive data being sent.
• System Configuration
  Setup default error messages so that unexpected errors do not disclose sensitive information.
• Architecture and Design
