Authenticated arbitrary file deletion via unchecked path concatenation
Published Oct 12, 2025 · Updated Oct 12, 2025
Path traversal in RainyGao DocSys 2.02.0 through 2.02.36 allows remote authenticated users to delete server files via deleteDoc.do. The deleteDoc_FSM path concatenates attacker-controlled path and name values into localDocPath, then FileUtil.delFileOrDir recursively deletes that target without restricting paths or filenames. A low-privileged DocSys account can therefore remove any file accessible to the service process, causing data loss or service interruption.
