CWE-377: DEPRECATED: Insecure Temporary File

Weakness ID: 377
Vulnerability Mapping: PROHIBITED This CWE ID must not be used to map to real-world vulnerabilities
Abstraction: Class Class - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.

Shows the description and diagram, platforms, mitigations, consequences, relationships, memberships, and content history. For users who are interested in more notional aspects of a weakness. Example: educators, technical writers, and project/program managers. For users who are concerned with the practical application and details about the nature of a weakness and how to prevent it from happening. Example: tool developers, security researchers, pen-testers, incident response analysts. For users who are mapping an issue to CWE/CAPEC IDs, i.e., finding the most appropriate CWE for a specific issue (e.g., a CVE record). Example: tool developers, security researchers. For users who wish to see all available information for the CWE/CAPEC entry. For users who want to customize what details are displayed.

+ Description
This entry has been deprecated. It was focused only on the affected resource (temporary file) and not the behavior or mistake that produced the insecure temporary file, which caused confusion and incorrect mappings.
+ Vulnerability Mapping Notes
Usage PROHIBITED
(this CWE ID must not be used to map to real-world vulnerabilities)
Reasons Deprecated, Frequent Misuse, Frequent Misinterpretation

Rationale

This CWE entry has been deprecated.

Comments

This entry has multiple widespread interpretations by CWE analysts, partially due to its ambiguous name. It combines information from three different taxonomies, but each taxonomy is talking about a slightly different issue. See Maintenance Notes.
