CVE-2019-11073
A Remote Code Execution vulnerability exists in PRTG Network Monitor before 19.4.54.1506 that allows attackers to execute code due to insufficient sanitization when passing arguments to the HttpTransactionSensor.exe binary.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
