Authenticated file placement via traversal filename
Published Jan 28, 2026 · Updated Jan 28, 2026
Path traversal in jishenghua jshERP 3.0 through 3.6 allows remote authenticated users to place files via a crafted upload filename. The uploadConfig handler passes the user-supplied MultipartFile to DefaultPluginOperator.uploadConfigFile, which writes its bytes with Files.write without restricting the resolved destination. A valid X-Access-Token is required; traversal segments can place or overwrite attacker-controlled content outside the plugin configuration directory.
