|---|
| 説明 | There is a path traversal vulnerability in webtorrent library 2.8.5 .The library component treats file.path as a normal file name/path component without validating whether it contains malicious path traversal sequences.. And the import information about this vulnerability is as follows:
Core location: torrent.js
Key code: In getFileModtimes(), the following line is used:
Relevant context: file.path originates from the file list in the .torrent metadata and is therefore attacker-controlled input.
Underlying issue:
Dangerous input: If an attacker sets file.path to a value such as ../../../etc/hosts, the value contains ../ segments that can escape the intended download directory.
Result: path.join(this.path, file.path) may resolve to a path outside the configured download root, allowing access to files outside the expected directory boundary. |
