Paessler PRTG Network Monitor OS Command Injection Vulnerability
Paessler PRTG Network Monitor contains an OS command injection vulnerability that allows an attacker with administrative privileges to execute commands via the PRTG System Administrator web console.
A remote attacker, with administrative privileges, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2025-02-25 under CISA BOD 22-01.
This is a OS Command Injection (CWE-78) vulnerability in Paessler PRTG Network Monitor. An issue was discovered in PRTG Network Monitor before 18.2.39. An attacker who has access to the PRTG System Administrator web console with administrative privileges can exploit an OS command injection vulnerability (both on the server and on devices) by sending malformed parameters in sensor or notification management scenarios. Exploitation requires remote network access, low attack complexity, an administrative account, and no user interaction required.
