CVE-2025-41753

CriticalCVSS 9.8
Published: Translated: NVD NIST

Summary

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.

Risk Assessment

The risk includes unauthorized file access and modification, potentially leading to confidentiality, integrity, and availability breaches of the system.

Recommendation

It is recommended to update the device software to a version containing a fix for this vulnerability or apply appropriate network security measures to restrict access.
