Arbitrary code execution via uncontrolled search paths
Published May 14, 2024 · Updated Apr 24, 2025
Uncontrolled search-path loading in affected B&R software allows local users to execute arbitrary code through crafted DLLs or executables. The applications follow the Windows DLL search and load order and inadequately check integrity before executing code from untrusted locations. Exploitation requires authenticated access to an affected node and the ability to place or replace a file that legitimate software loads.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
