CVE-2021-31477

Remote code execution via hard-coded credentials

Published Jun 16, 2021 · Updated Aug 3, 2024

Hard-coded credentials in GE Vernova Reason RPV311 14A03 and earlier allow remote attackers to execute code as the download user. The device firmware and filesystem embed fixed credentials that the authentication path accepts, granting access to the download account. No prior authentication is required, but network access to the appliance's private industrial or substation network is necessary; control is limited to the download user's privileges.
