Name: Path Equivalence: 'file.name' (Internal Dot)

The product accepts path input in the form of internal dot ('file.ordir') 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.

Vulnerability Mapping Notes

Justification : 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.
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.

NotesNotes

An improper attempt to remove the internal dots from the string could lead to CWE-181 (Incorrect Behavior Order: Validate Before Filter).
