CWE-215 Insertion of Sensitive Information Into Debugging Code

The product inserts sensitive information into debugging code.

• Confidentiality: Read Application Data — Sensitive information could be exposed if the debugging code is not disabled in production.

• [Implementation] Do not leave debug statements that could be executed in the source code. Ensure that all debug information is eradicated before releasing the software. • [Architecture and Design] Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.

• 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.)

• CVE-2004-2268: Password exposed in debug information. • CVE-2002-0918: CGI script includes sensitive information in debug messages when an error is triggered. • CVE-2003-1078: FTP client with debug option enabled shows password to the screen.
