An issue was discovered in Ozeki NG SMS Gateway through 4.17.6. The outbox functionality of the TXT File module can be used to delete all/most files in a folder. Because the product usually runs as NT AUTHORITYSYSTEM, the only files that will not be deleted are those currently being run by the system and/or files that have special security attributes (e.g., Windows Defender files).
