SYSTEM code execution via unrestricted upload path
Published Sep 7, 2023 · Updated Sep 26, 2024
Arbitrary file write in RDPngFileUpload.dll in IRM Next Generation 1.0.0.0 allows remote authenticated users to execute code as SYSTEM. The RDPng File Upload service runs as SYSTEM, reads content and destination values from the FileUploads SQL table, and writes content to the supplied path without blocking traversal into protected directories. A management-session gate normally applies; paired hard-coded credentials remove the need for assigned credentials, and a written DLL or web shell grants host compromise.
