CVE-2022-34576Public exploitNetwork attack vector

Unauthenticated configuration disclosure via unprotected export endpoint

Published Jul 25, 2022 · Updated Aug 3, 2024

Information disclosure in WAVLINK WN535 G3 firmware M35G3R.V5030.180927 allows remote attackers to read device configuration without authentication. The /cgi-bin/ExportAllSettings.sh endpoint returns the current configuration, including the administrator password, without enforcing authorization; publicly available information reverses its encryption. Network access to the device is sufficient, and the demonstrated consequence is disclosure of configuration secrets rather than arbitrary code execution.
