CWE-46: Path Equivalence: 'filename ' (Trailing Space)
Weakness ID : 46
Structure : Simple
Abstraction : Variant
Description
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.
