RUGGEDCOM RM1224 LTE(4G) EU: Improper Neutralization of Special Elements used in a Command

Published Updated By the CyberSecBulletin desk

CVE-2024-50572 is a high-severity improper neutralization of special elements used in a command vulnerability in RUGGEDCOM RM1224 LTE(4G) EU from Siemens, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version V8.2 as the first without the flaw, so updating RUGGEDCOM RM1224 LTE(4G) EU to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.67% chance of exploitation within 30 days, higher than 53% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update RUGGEDCOM RM1224 LTE(4G) EU to V8.2 or a later version.
  2. Update RUGGEDCOM RM1224 LTE(4G) NAM to V8.2 or a later version.
  3. Update SCALANCE M804PB to V8.2 or a later version.

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
