CVE-2020-10973Public exploitNetwork attack vector

Unauthenticated configuration disclosure via ExportAllSettings

Published May 7, 2020 · Updated Aug 4, 2024

Information disclosure in Wavlink WN530HG4, WN531G3, WN533A8, and WN551K1 allows remote attackers to read configuration data. The /cgi-bin/ExportAllSettings.sh endpoint returns a crafted POST response containing the current device configuration, including the administrator password; available decryption information makes the contents recoverable. No authentication is required, so any network-reachable device is exposed; the demonstrated consequence is confidentiality loss and credential disclosure without reported modification or service interruption.
