Administrative compromise via undocumented privileged account
Published Dec 23, 2021 · Updated Sep 16, 2024
Hidden administrative account in mySCADA myPRO 8.20.0 and earlier allows remote attackers to gain administrative access. The product embeds an undocumented administrator account that the regular web interface neither displays nor permits administrators to delete or change. No preexisting account or user interaction is required; use of the concealed account grants administrative control over the SCADA runtime and connected industrial processes.
