PRTG Network Monitor before 18.3.44.2054 allows a remote authenticated attacker (with read-write privileges) to execute arbitrary code and OS commands with system privileges. When creating an HTTP Advanced Sensor, the user's input in the POST parameter 'proxyport_' is mishandled. The attacker can craft an HTTP request and override the 'writeresult' command-line parameter for HttpAdvancedSensor.exe to store arbitrary data in an arbitrary place on the file system. For example, the attacker can create an executable file in the \Custom Sensors\EXE directory and execute it by creating EXE/Script Sensor.

Security readout for executives and security teams

This flaw lets a logged-in PRTG user with read-write privileges turn sensor configuration into system-level code execution. It is not described as anonymous exploitation, but compromise of a privileged PRTG account could become full host compromise. Organizations running PRTG Network Monitor earlier than 18.3.44.2054, especially where non-core administrators have read-write or sensor-management privileges. Exposure depends on authenticated access to PRTG, not anonymous internet access. Treat this as high priority where affected PRTG versions remain in use. PRTG often monitors critical infrastructure, and a privileged account compromise could lead to system-level control of the monitoring server. Mitigation focus: Upgrade PRTG Network Monitor to 18.3.44.2054 or later per Paessler guidance.; Restrict read-write PRTG access to trusted administrators only.; Review and remove unnecessary sensor creation privileges..
