Remote code execution via unvalidated file paths
Published Apr 13, 2021 · Updated Aug 3, 2024
Path traversal in Schneider Electric C-Bus Toolkit 1.15.7 and earlier allows remote attackers to execute code through C-Gate commands. The C-Gate 2 Service uses a user-supplied path in file operations without validating that the resolved path remains in an intended directory. Authentication is nominally required but bypassable, and successful exploitation runs attacker-controlled code as SYSTEM.

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.
