MINOVA TTA Information Disclosure and Credential Exposure

Information disclosure and exposure of authentication FTP credentials over the debug port 1604 in the MINOVA TTA service. This allows unauthenticated remote access to an active FTP account containing sensitive internal data and import structures. In environments where this FTP server is part of automated business processes (e.g. EDI or data integration), this could lead to data manipulation, extraction, or abuse.  Debug ports 1602, 1603 and 1636 also expose service architecture information and system activity logs
