A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.14.1), RUGGEDCOM ROX RX1400 (All versions < V2.14.1), RUGGEDCOM ROX RX1500 (All versions < V2.14.1), RUGGEDCOM ROX RX1501 (All versions < V2.14.1), RUGGEDCOM ROX RX1510 (All versions < V2.14.1), RUGGEDCOM ROX RX1511 (All versions < V2.14.1), RUGGEDCOM ROX RX1512 (All versions < V2.14.1), RUGGEDCOM ROX RX1524 (All versions < V2.14.1), RUGGEDCOM ROX RX1536 (All versions < V2.14.1), RUGGEDCOM ROX RX5000 (All versions < V2.14.1). The command line interface of affected devices insufficiently restrict file read and write operations for low privileged users. This could allow an authenticated remote attacker to escalate privileges and gain root access to the device.
This plugin only works with Tenable.ot.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.
Siemens has released an update and recommends users update to v2.14.1 or later version.
Siemens has identified the following specific workarounds and mitigations users can apply to reduce the risk:
- Apply the principle of least privileges for accounts configured on the affected devices.
As a general security measure, Siemens strongly recommends users protect network access to devices with appropriate
mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends users configure the
environment according to SiemensΓ’ΒΒ operational guidelines for industrial security and follow the recommendations in the
product manuals.
Additional information on industrial security by Siemens can be found at: https://www.siemens.com/industrialsecurity
