Vendor and ecosystem advisories describing this.

  • VDE-2020-015WAGO: Web Based Management - Code Execution Vulnerability2020-06-10csaf · wago_psirtDE

    The Web-Based Management (WBM) of WAGOs programmable logic controller (PLC) is typically used for administration, commissioning and updates. An attacker needs an authorized login with administrative privileges on the device in order to exploit the herein mentioned vulnerability. An authenticated attacker who has access to the Web Based Management (WBM) could use the software upload functionality to install software package with root privileges. This fact could be potentially used to manipulate the device or to get control of the device.
