Title:PRTG Network Monitor < 20.1.57.1745 RCE Vulnerability
Summary:PRTG Network Monitor is prone to an unauthenticated remote code; execution (RCE) vulnerability.
Description:Summary:
PRTG Network Monitor is prone to an unauthenticated remote code
execution (RCE) vulnerability.

Vulnerability Insight:
With a carefully crafted POST request, a possible attacker can perform an RCE
by executing a UNC path on the PRTG core server system with the security context of the PRTG core server service,
without the need of an authenticated session.

By utilizing the what parameter of the screenshot function that is used in the Contact Support form in PRTG, for
example, an attacker is able to inject a crafted, URI-compatible UNC path that is executed as part of the caller
chain down to the Chromium engine to create the screenshot.

Affected Software/OS:
PRTG Network Monitor versions 19.2.50 through 20.1.56.

Solution:
Update to version 20.1.57.1745 or later.

CVSS Score:
7.5

CVSS Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P
