CVE-2020-35756Public exploitNetwork attack vector

Unauthenticated password disclosure via GETPASS

Published May 3, 2021 · Updated Aug 4, 2024

Authentication bypass in Libre Wireless LS9 LS1.5/p7040 allows remote attackers to disclose the device configuration password via TCP port 7777. The luci_service daemon accepts the GETPASS command without authenticating the requester and returns the configured password in cleartext. Any attacker able to reach port 7777 can obtain the credential; the documented impact is information disclosure, with no reported direct integrity or availability effect.
