Insertion of Sensitive Information into Externally-Accessible File or Directory

The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information.

Informations

Modes Of Introduction

Implementation : OMISSION: This weakness is caused by missing a security tactic during the architecture and design phase.
Operation : OMISSION: This weakness is caused by missing a security tactic during the architecture and design phase.

Applicable Platforms

Language

Class: Not Language-Specific (Undetermined)

Common Consequences

Scope Impact Likelihood
ConfidentialityRead Files or Directories

Observed Examples

Reference Description
CVE-2018-1999036SSH password for private key stored in build log

Potential Mitigations

Phases : Architecture and Design // Operation // System Configuration
Do not expose file and directory information to the user.

Detection Methods

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.)
Effectiveness : High

Vulnerability Mapping Notes

Rationale : 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.
Comments : 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-95 WSDL Scanning
This attack targets the WSDL interface made available by a web service. The attacker may scan the WSDL interface to reveal sensitive information about invocation patterns, underlying technology implementations and associated vulnerabilities. This type of probing is carried out to perform more serious attacks (e.g. parameter tampering, malicious content injection, command injection, etc.). WSDL files provide detailed information about the services ports and bindings available to consumers. For instance, the attacker can submit special characters or malicious content to the Web service and can cause a denial of service condition or illegal access to database records. In addition, the attacker may try to guess other private methods by using the information provided in the WSDL files.

Notes

Depending on usage, this could be a weakness or a category. Further study of all its children is needed, and the entire sub-tree may need to be clarified. The current organization is based primarily on the exposure of sensitive information as a consequence, instead of as a primary weakness.
There is a close relationship with CWE-552, which is more focused on weaknesses. As a result, it may be more appropriate to convert CWE-538 to a category.
