Sensitive information disclosure via management responses
Published May 19, 2021 · Updated Aug 3, 2024
Information disclosure in ZTE ZXCDN 7.01 through IAMV7.01.01.02 allows remote authenticated users to obtain sensitive information. The vendor describes the management system as returning information that attackers can analyze, but it does not disclose the endpoint, parameter, or faulty operation responsible. Exploitation requires access to the management interface and yields confidentiality impact without reported integrity or availability effects.
