Common Weakness Enumeration

CWE-49

Weakness Allowed

Path Equivalence: 'filename/' (Trailing Slash)

Abstraction: Variant · Status: Incomplete

API response cwe.mitre.org

The product accepts path input in the form of trailing slash ('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.

Mapping guidance

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

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.
