EPSS · scored 2026-10-22

The object name of a dynamically created BACnet File Object is interpreted as a file path without sufficient validation. Because relative paths are not limited to the intended directory, an unauthenticated remote attacker can traverse outside of it and read or overwrite arbitrary files on the device, which may lead to full system compromise.

  • VDE-2025-102WAGO: Multiple Devices are affected by a Vulnerability in BACnet IP Stack2026-10-01csaf · wago_psirtDE

    Multiple WAGO devices are affected by a vulnerability in the dynamic creation of BACnet File Objects. The object name is used as a file path without sufficient validation and is not restricted to the intended directory, so relative paths can be used to reach files elsewhere in the file system.
