Path traversal in ChangingTec MOTP 3.11 and earlier allows remote authenticated users with administrator access to read arbitrary system files. TWCERT/CC has not disclosed the affected endpoint, parameter, or path-validation operation that accepts traversal input. Exploitation requires MOTP administrator privilege, and the documented consequence is file disclosure without reported modification or service interruption.
