Code execution via unvalidated extractPages path
Published Aug 11, 2021 · Updated Aug 4, 2024
Arbitrary file write in Foxit Reader and PhantomPDF before 10.1.4 allows attackers to execute code through JavaScript. The extractPages and CombineFiles functions neither restrict the output file type nor validate the supplied file path before writing. The vulnerable JavaScript must execute inside the Windows desktop application; a successful write can place attacker-controlled content at an arbitrary path and enable code execution.
