A Write to Arbitrary Location in Disk vulnerability exists in PRTG Network Monitor 19.1.49 and below that allows attackers to place files in arbitrary locations with SYSTEM privileges (although not controlling the contents of such files) due to insufficient sanitisation when passing arguments to the phantomjs.exe binary.
