=== Path traversal
|
||||
|
||||
A path(directory) traversal is a vulnerability where an attacker is able to access or store files and directories outside
|
||||
the location where the application is running. This may lead to reading files from other directories and in case of a file
|
||||
upload overwriting critical system files.
|
||||
|
||||
=== How does it work?
|
||||
|
||||
For example let's assume we have an application which hosts some files and they can be requested in the following
|
||||
format: `http://example.com/file=report.pdf` now as an attacker you are interested in other files of course so
|
||||
you try `http://example.com/../../../../../etc/passwd`. In this case you try walk up to the root of the filesystem
|
||||
and then go into `/etc/passwd` to gain access to this file. The `../` is called dot-dot-slash which is another name
|
||||
for this attack.
|
||||
|
||||
Of course this is a very simple example and in most cases this will not work as frameworks implemented controls for
|
||||
this, so we need to get a little more creative and start encoding `../` before the request is sent to the server.
|
||||
For example if we URL encode `../` you will get `%2e%2e%2f` and the web server receiving this request will decode
|
||||
it again to `../`.
|
||||
|
||||
Also note that avoiding applications filtering those encodings double encoding might work as well. Double encoding
|
||||
might be necessary in the case where you have a system A which calls system B. System A will only decode once and
|
||||
will call B with the still encoded URL.
|
||||
|
||||
Now let's try some examples
|
||||
|
||||
1. Example with upload where you have to overwrite one of the files
|
||||
1a Example upload where developer implemented a fix by removing ../ from the path
|
||||
1b No longer using name of user to store file so you need proxy to intercept
|
||||
2. Example with download for example the idea is to download a pdf but there is also a txt file
|
||||
3. Same as 2 with blacklisting implemented (see example from Workpress plugin)
|
||||
4. Zip path traversal where you have to create a zip file which overwrites a file in another directory
|
||||
|
||||
|
||||
- Run app with least priviledge
|
||||
- Before storing the file calculate the location
|
||||
- Same for reading is it actually reading from the directory you allow

=== Retrieving other files with a path traversal

is possible to retrieve other files from the system. In this assignment try to find a file called `secret.txt`

Finally the upload is no longer vulnerable at least help us to verify :-)

||||
In this assignment you need to get the contents of the following file:
|
||||
|
||||
|===

||||

|
||||
|
||||
|`operatingSystem:os[]`

|
||||
=== Path traversal mitigation
|
||||
|
||||
As we saw in the previous assignments protecting a file upload can be a daunting task. The thing comes down to trusting
|
||||
input without validating it.
|
||||
In the examples shown before a solution might be to not trust user input and create a random file name on the
|
||||
server side.
|
||||
|
||||
If you really need to save it based on user input the best way to keep you save is to check the canonical path the
|
||||
file will be saved. For example in Java:
|
||||
|
||||
[source]
|
||||
----
|
||||
var multiPartFile = ...
|
||||
var targetFile = new File("/tmp", multiPartFile.getOriginalName());
|
||||
var canonicalPath = targetFile.getCanonicalPath();
|
||||
|
||||
if (!canonicalPath.startWith("/tmp") {
|
||||
throw new IllegalArgumentException("Invalid filename");
|
||||
}
|
||||
|
||||
IOUtils.copy(multiPartFile.getBytes(), targetFile);
|
||||
----
|
||||
|
||||
The canonical path function will resolve to a absolute path, removing `.` and `..` etc. By checking whether the canonical
|
||||
path is inside the expected directory the path traversal will be avoided.
|
||||
|
||||
|
||||
For path traversals while retrieving one can apply the same technique described above but as a defence in depth you
|
||||
can also implement a mitigation by running the application under a specific not privileged user which is not allowed to read and write
|
||||
in any other directory.
|
||||
|
||||
Make sure that in any case you build detection for catching these cases but be careful with returning explicit information
|
||||
to the user. Every small detail might give the attacker knowledge about your system.
|
||||
|
||||
==== Spring Boot protection
|
||||
|
||||
By default Spring Boot has protection for usage of for example `../` in a path. The implementation can be found in
|
||||
`StrictHttpFirewall` class. This will protect endpoint where the user input is part of the `path` like `/test/1.jpg`
|
||||
if you replace `1.jpg` with `../../secret.txt` it will block the request. With query parameters that protection
|
||||
will not be there.
|
||||
|
||||
In the lesson about "File uploads" more examples of vulnerabilities are shown.
