Unauthenticated file disclosure via external entity resolution
Published Jul 19, 2025 · Updated Jul 21, 2025
XML external entity injection in Jinher OA 1.2 allows remote attackers to read server files through crafted ProjectScheduleDelete.aspx requests. The endpoint parses attacker-supplied XML with external entity resolution enabled, so a crafted DTD reads a local file and sends its contents to an attacker-controlled HTTP server. No authentication or user interaction is required; the demonstrated impact is disclosure of files accessible to the server process.
