CVE-2019-11073Network attack vector

Remote code execution via unsanitized sensor arguments

Published Mar 16, 2020 · Updated Aug 4, 2024

Remote Code Execution in Paessler PRTG Network Monitor before 19.4.54.1506 allows remote authenticated administrators to execute code. HttpTransactionSensor.exe passes attacker-controlled HTTP Transaction Sensor settings without sufficient sanitization, allowing injected arguments to alter command execution. Exploitation requires an administrator to create a sensor and configure specific settings; successful execution can compromise confidentiality, integrity, and availability on the PRTG host.
