Authenticated file disclosure across directory boundaries
Published Mar 5, 2021 · Updated Aug 3, 2024
Incorrect authorization in ZTE ZXHN H196Q V9.1.0C2 allows remote authenticated users to read files outside authorized directories. ZTE states only that specific operations cross directory authorization boundaries; it does not disclose the affected interface, path-handling logic, or file-access routine. Exploitation requires low-privilege access from an adjacent network and exposes file contents without reported modification or service interruption.
