RUGGEDCOM i800: Exposure of Sensitive Information to an Unauthorized Actor

Published Updated By the CyberSecBulletin desk

CVE-2023-52237 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in RUGGEDCOM i800 from Siemens, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions V4.3.10, 4.3.10 as the first without the flaw, so updating RUGGEDCOM i800 to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.44% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update RUGGEDCOM i800 to V4.3.10 or 4.3.10, whichever matches your release line, or a later version.
  2. Update RUGGEDCOM i800NC to V4.3.10 or 4.3.10, whichever matches your release line, or a later version.
  3. Update RUGGEDCOM i801 to V4.3.10 or 4.3.10, whichever matches your release line, or a later version.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How developers prevent this class of flaw

  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
