CVE-2025-41753
Path traversal in dynamically created BACnet File Objects
Critical9.3EPSS 0.59%

- CERTVDE
Description
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.
