| Описание | # Directory Traversal (Chroot Escape)
## Description
It is possible for an unauthenticated user to perform a directory traversal attack using multiple different FTP commands and read and write to arbitrary locations on the filesystem due to the lack of a well-written chroot jail in `compose_abspath`.
## Reproduction Steps
To reproduce this vulnerability, connect via `netcat <ip> <port>` and write to the FTP server socket the following:
```
MKD ../../../../../tmp/itworked
```
Then, `ls /tmp/itworked` from terminal to verify that the folder was created.
## Mitigation
Properly sanitize paths. |
