CVE-2020-6865

Sensitive information disclosure via verbose error responses

Published Apr 30, 2020 · Updated Aug 4, 2024

Information disclosure in ZTE OSCP V16.19.10 and V16.19.20 allows remote authenticated users to obtain sensitive data via failed requests. The controller returns internal error-code locations directly to a caller instead of suppressing failure details in its response. Low-privileged access from an adjacent network is required, and the documented consequence is confidentiality exposure without integrity or availability impact.
