Unauthenticated file disclosure via controllable log path
Published Aug 20, 2021 · Updated Aug 4, 2024
Path traversal in Skycaiji 1.3 allows remote attackers to read sensitive server files through the administrative log-view endpoint. The Tool controller's log action accepts the file query parameter as a filesystem path and returns the referenced file without restricting it to the log directory. No authentication or user interaction is required, and disclosure is limited to files readable by the web application's process.
