|
This module exploits a directory traversal bug in Yaws v1.9.1 or less.
|
||||||
|
The module can only be used to retrieve files. However, code execution might
|
||||||
|
be possible. Because when the malicious user sends a PUT request, a file is
|
||||||
|
actually created, except no content is written.
