CVE-2021-34560

Credential disclosure via autocomplete-enabled password field

Published Aug 31, 2021 · Updated Sep 16, 2024

Credential exposure in Pepperl+Fuchs WirelessHART-Gateway 3.0.9 and earlier allows attackers to recover a user's stored password. The gateway's web form leaves autocomplete enabled on its password input, causing the browser to retain and later supply the credential. Exploitation requires control of a computer whose user has logged in to the gateway at least once; the documented consequence is disclosure of that stored credential.
