CVE-2022-47891Network attack vector

Administrator password reset via device identifier recovery

Published Oct 3, 2023 · Updated Sep 6, 2024

Use of hard-coded credentials in Riello UPS NetMan 204 all versions allows remote attackers to reset the administrator password over the network. The /cgi-bin/recoverpassword.cgi workflow treats the device MAC address and serial number as sufficient input to authorize the reset. Network access and knowledge of both identifiers are required; successful use replaces the administrator credential and grants control of the management account.
