CVE-2020-25754

Description

An issue was discovered on Enphase Envoy R3.x and D4.x devices. There is a custom PAM module for user authentication that circumvents traditional user authentication. This module uses a password derived from the MD5 hash of the username and serial number. The serial number can be retrieved by an unauthenticated user at /info.xml. Attempts to change the user password via passwd or other tools have no effect.
