Name: Debug Messages Revealing Unnecessary Information

The product fails to adequately prevent the revealing of unnecessary and potentially sensitive system information within debugging messages.

CWE Description

Debug messages are messages that help troubleshoot an issue by revealing the internal state of the system. For example, debug data in design can be exposed through internal memory array dumps or boot logs through interfaces like UART via TAP commands, scan chain, etc. Thus, the more information contained in a debug message, the easier it is to debug. However, there is also the risk of revealing information that could help an attacker either decipher a vulnerability, and/or gain a better understanding of the system. Thus, this extra information could lower the "security by obscurity" factor. While "security by obscurity" alone is insufficient, it can help as a part of "Defense-in-depth".

Potential Mitigations

Phases : Implementation
Ensure that a debug message does not reveal any unnecessary information during the debug process for the intended response.

Vulnerability Mapping Notes

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : 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.

Related Attack Patterns

CAPEC-ID Attack Pattern Name
CAPEC-121 Exploit Non-Production Interfaces

An adversary exploits a sample, demonstration, test, or debug interface that is unintentionally enabled on a production system, with the goal of gleaning information or leveraging functionality that would otherwise be unavailable.
