CVE-2020-14031

Estado: ModificadaAlta (7.2)—

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 AUTHORITY\SYSTEM, 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).
