CWE-46

Allowed

Path Equivalence: 'filename ' (Trailing Space)

Abstraction: Variant · Status: Incomplete

API response cwe.mitre.org

The product accepts path input in the form of trailing space ('filedir ') without appropriate validation, which can lead to ambiguous path resolution and allow an attacker to traverse the file system to unintended locations or access arbitrary files.

CAPEC-649: Adding a Space to a File Extension

An adversary adds a space character to the end of a file extension and takes advantage of an application that does not properly neutralize trailing special elements in file names. This extra space, which can be difficult for a user to notice, affects which default application is used to operate on the file and can be leveraged by the adversary to control execution.
