CVE-2021-33215Public exploitNetwork attack vector

Authenticated directory listing via API path traversal

Published Jul 7, 2021 · Updated Aug 3, 2024

Path traversal in CommScope Ruckus IoT Controller 1.7.1.0 and earlier allows remote authenticated users to list filesystem directories. The /VRIOT/ops/docker/webservice/web.py script uses the API-supplied path parameter without confining traversal to an authorized directory. A valid token is required, and the root-run web application exposes directory names and metadata throughout the controller filesystem.
