Arbitrary file disclosure via relative path traversal
Published Dec 4, 2025 · Updated Feb 25, 2026
Relative path traversal in NI System Web Server for LabVIEW 2009 through 2012 allows remote attackers to read arbitrary files via crafted requests. The server resolves attacker-controlled relative path sequences outside the intended web root instead of confining requests to permitted files. No authentication or user interaction is required; NI has not disclosed the affected request handler or parameter, and the documented consequence is file read only.

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.
